1 ,11, 21, 1211, 111221,--------

What will be the next number in this sequence... Don't google for the answer.just try it out.

312211....

13112221...

ha ha, that was easy.

π..raj got it with the first answer ..π

312211.....hey i too answered correctly....

but how about, the guys who got it correct give the explanation also??? π

1 ,11, 21, 1211, 111221

Every next number is formed by reading out the previous number and counting how many times the number appears, in that sequence. That is, second number is formed by saing : One One.

Third Number is reading out the second number: Two One

One, One One, Two One, One Two One One, One One One Two Two One

**What is next in the sequence**

An easy one for you all:

M, T, W, T,___ , ___ , ___

Think Think ??? A dairy milk for the correct answer. π

T S S

is it correct? the days in the week .

is it correct? the days in the week .

Oooooooo..Impressesed with the explanation but unfortunately your answer is wrong so dairy milk is mine.πEnglish-ScaredT S S

is it correct? the days in the week .

Correct answer is F,S, S not T,S,S Ha ha ha ...π

aha shalini you are right , but as i got the idea correct i guess we can have one each.π

O, T, T, F, F, S, S, E, _?_ , _?_ , _?_ , _?_ π

Anyone?

Anyone?

So simple, N,T,E,T . Am i right? πThe_Big_KO, T, T, F, F, S, S, E, _?_ , _?_ , _?_ , _?_ π

Anyone?

Buy a one π because i have finished mine one.English-Scaredaha shalini you are right , but as i got the idea correct i guess we can have one each.π

Sure will buy one by you name and will complete it, and the answer is N,T E,T T,F F,S as biggie gave 8 dashes to answerπ.

i think you have answer only half of it , guess busy eating the dairy milkπ

i think you have answer only half of it , guess busy eating the dairy milkπ

Mr Scared, so what blanks are 8 but '?' are 4 only na. By the way, don't expect its correct answer. You will come to know it after some years I guess. Not sure even πEnglish-ScaredSure will buy one by you name and will complete it, and the answer is N,T E,T T,F F,S as biggie gave 8 dashes to answerπ.

I nearly messed up a lab experiment test because I forgot that darn sequence π

I remotely recall that we used to remember the seq as"B.B ROY Great Britain had a Very Good Wife "

what else could we do.. it was so adhoc π

what else could we do.. it was so adhoc π

hey yep yes , how can i forget this . now i remember π

Even I can also recall it now but I read it in my 12th standard(not in engineering) in resistors chapter.

@Durga even I also learnt that way "B.B ROY Great Britain had a Very Good Wife". You won't believe it but this way of learning was in my physics book.

Ash hope this way you don't mess your next exam π

Ash hope this way you don't mess your next exam π

Well, who needs it when you have the engineer's best friend, the multimeter? πdurgaπ

Ash hope this way you don't mess your next exam π

Well done guys... B b Roy method is kind of a standard all over india... But if we do a google on the sequence, we can find lots of other funny sentence also...some are bit offensive... π

The series ends in .....,F,S,S. Which I believe, translates into Friday Saturday and Sunday. Can someone confirm?

Well done shiwa π. Your answer & explanation is absolutely correct.shiwa436.....,F,S,S.

Friday Saturday and Sunday.

Now check the following:

https://www.crazyengineers.com/forum/chillax-chit-chat/13743-illogical-questions.html

Complete the following very simple sequence:

364, 361, 19, 16, 4, 1, __ ?

364, 361, 19, 16, 4, 1, __ ?

ha,

How many numbers do you need? Next number alone is enough or should i continue the series?

Anyways, the series continues as follows.

364, 361, 19, 16, 4, 1,

well, this can further continue in complex numbers, like 1.414j, -3+1.414j, square root(-3+1.414j) etc..ππ

How many numbers do you need? Next number alone is enough or should i continue the series?

Anyways, the series continues as follows.

364, 361, 19, 16, 4, 1,

**1, -2**

the logic is, subtract three from 1st number, take square root, again subtract three and go on.well, this can further continue in complex numbers, like 1.414j, -3+1.414j, square root(-3+1.414j) etc..ππ

answer 1,-2,and then sqrt of -2 and so on

364 -361 =3

19^2 =361

19 -3 =16

4^2=16

4-3=1

1^1 =1

364 -361 =3

19^2 =361

19 -3 =16

4^2=16

4-3=1

1^1 =1

oops!

look like SS has already replied

Well Good Scorpion & Durga but I asked only for 1 no in the seriesπ. Not the list extending to complex numbers .silverscorpionha,

ok that was clear.

here is one more.

Do you know numbers and letters? Now find the next number in the series.

5.. 15 ..5.. 18.. 5.. 24 ..14.. 20.. ?

Looking at onE, twO, threE, fouR, fivE, siX, seveN, eighT, it should be apparent that we are looking at the last letter of each number (in English) which is then converted to its position in the alphabet (E=5, O=15, etc.)

-Crazy

ES Salutes to Crazy Boy.π

the next number is 27......... then 26......

oopps the answer is already given huhhhhhhhhh

using set of numbers repeating it two times..... find out a number as given below 312132......

the speciality in this number is that 1, 2, and 3 is used two times and between two 3's there are three numbers and between two 2's there are two numbers and between two one's there is one number..... find a number using a set of 1,2,3,4 repeatin the numbers two times with the same concept given above......

Someone please post some puzzle out there... I am feeling very bored today. Mods spare me for this post.

Hey..you are the best. how about you make an unbreakable sequence and test our skills? that will be fun.crazyboySomeone please post some puzzle out there... I am feeling very bored today. Mods spare me for this post.

hey Crazy, if you are getting bored even today, then here is another one

Find next number in the series...

1/1, 3/2, 7/5, 17/12, 41/29, ?

1/1, 3/2, 7/5, 17/12, 41/29, ?

1/1, 3/2, 7/5, 17/12, 41/29,

**99/70**

The successive term for a/b is formed as (a + 2b) / (a + b).

PS:where a = 1, b =1 in starting and continue till end.

Waiting for the next one to come.. π

-CrazyBoy

Woo!!π

Now try this.

Add a '+' or a '-' sign in between the numbers so that the result is '100'. You cannot interchange the numbers here, they should be in the sequence from 1-9 as given below. Find out the different ways that makes the equation correct.

123456789 = 100

123 -45 -67 + 89 = 100ππ

Yup that's the way. now find out other such equations.

I am working on other sequences.. lets see If i can get a few more solution for this puzzle.

-Crazy π

hey, you cannot use '*' , i mean should not use multiplcation here. Get the equation correct with only a + or - sign.

so, we'll consider the second one.

Is it 1/1, 3/2, 7/5, 17/12, 41/29,

**91/64**?

hey what is the rule you applied here??

Buddy I am giving you general solution... so that you wont ask me the next number from the same sequence πg_rakesh2Is it 1/1, 3/2, 7/5, 17/12, 41/29,91/64?

(a+2b)/(a+b)

=(91+2*64)/(91+64) = 219/155

Next please

here goes the next list:

4 12 6 12 36 18 36 ?

9 4 10 5 11 6 ?
