# Next number in sequence

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

What will be the next number in this sequence... Don't google for the answer.just try it out.
raj87verma88 • Jan 12, 2009
312211....

ha ha, that was easy.
arunhero99 • Jan 13, 2009
π..raj got it with the first answer ..π
charumathi • Jan 13, 2009
arunhero99 • Jan 14, 2009
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

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 .

T S S
is it correct? the days in the week .
Oooooooo..Impressesed with the explanation but unfortunately your answer is wrong so dairy milk is mine.π

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
Kaustubh Katdare • Jan 20, 2009
O, T, T, F, F, S, S, E, _?_ , _?_ , _?_ , _?_ π

Buy a one π because i have finished mine one.
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

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 π

I nearly messed up a lab experiment test because I forgot that darn sequence π
durga ch • Jan 29, 2009
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
babloo0311 • Jan 29, 2009
hey yep yes , how can i forget this . now i remember π
shalini_goel14 • Jan 29, 2009
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.
durga ch • Jan 29, 2009

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? π
arunhero99 • Jan 30, 2009
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
shiwa436 • Feb 2, 2009
The series ends in .....,F,S,S. Which I believe, translates into Friday Saturday and Sunday. Can someone confirm?
shalini_goel14 • Feb 3, 2009
shiwa436
.....,F,S,S.

Friday Saturday and Sunday.

Now check the following:

shalini_goel14 • Feb 8, 2009
Complete the following very simple sequence:

364, 361, 19, 16, 4, 1, __ ?
silverscorpion • Feb 8, 2009
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, 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..ππ
durga ch • Feb 8, 2009
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

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

So Sequence is:

364, 361, 19, 16, 4, 1, 1 π

Never thought anyone would crack that... Nice talent.
Anyway. a much simpler one:

2,9,5,13,10,19,17, ?
rishna • Mar 24, 2009
2,9,5,13,10,19,17,27
arunhero99 • Mar 24, 2009
awesome ... 27 it is.
now, who wants to explain how the answer is 27?

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.. ?

5.. 15 ..5.. 18.. 5.. 24 ..14.. 20.. 5 (ninE)

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.)

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

syedaafaq • Mar 24, 2009
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......

Hey..you are the best. how about you make an unbreakable sequence and test our skills? that will be fun.
rishna • Mar 24, 2009
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, ?

@arunhero99 - Thanks buddy !!

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

rishna • Mar 24, 2009
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 = 100ππ

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

interesting one...

1) 1*2+3*4+5-6+78+9
2) 123+45-67+8-9

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

-Crazy π
rishna • Mar 25, 2009
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.
Ok...

123-4-5-6-7+8-9
123+4-5+67-89
12-3-4+5-6+7+89

π Crazy
rishna • Apr 2, 2009
solutions which i know...

123-45-67+89=100
12+3+4+5-6-7+89=100
12+3-4+5+67+8+9=100
1+23-4+56+7+8+9=100
1+23-4+5+6+78-9=100

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, ?

Is it 1/1, 3/2, 7/5, 17/12, 41/29, 91/64 ?
rishna • Apr 2, 2009
hey what is the rule you applied here??
g_rakesh2
Is it 1/1, 3/2, 7/5, 17/12, 41/29, 91/64 ?
Buddy I am giving you general solution... so that you wont ask me the next number from the same sequence π

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

arunhero99 • Apr 9, 2009
here goes the next list:

4 12 6 12 36 18 36 ?

9 4 10 5 11 6 ?

2 5 11 20 32 47 ?

13 18 16 21 19 ?

8 9 11 14 7 9 12 ?
g_rakesh2
Is it 1/1, 3/2, 7/5, 17/12, 41/29, 91/64 ?

its 99/70

π
and then
239/169
