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

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 😕

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.

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

Complete the following very simple sequence:

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

silverscorpion

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..😁😁

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 series😉. Not the list extending to complex numbers .

So Sequence is:

364, 361, 19, 16, 4, 1, 1 😁

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.)

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......

@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.. 😁

Woo!!😁

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

interesting one...

1) 1*2+3*4+5-6+78+9

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.
