It can be anything. These kinds of questions are silly.

But, this sequence is a famous one.

If you say out aloud how many of each digit is there (looking at contiguous subsustrings), you get the next term.

SO
1 = one
11 = one one
21 = two ones
1211 = one two one one
111221 = one one one two two ones

etc...

why not 31, 41 ..?

i dont understand why the answer is not 31,41 and how the series is 1211 and 111221

the line above is described by line below. First digit notifies the quantity and the following the type(number)

1
11(1 quantity of digit 1, describing the above line)
21(2 quantity of digit 1, describing the above line)
1211(1 quantity of digit 2, 1 quantity of digit 1, describing the above line)
111221(1 quantity of 1, 1 quantity of 2, 2 quantity of 1, describing the above line)
312211(3 quantity of 1, 2 quantity of 2, 1 quantity of 1, describing the above line)

Looks its

31
41
51

if you get this question you are allowed to wait for the moment when they say "Any questions for me?" And then, reply back with your own very difficult and stupid brainteaser.

i like/agree LOLer's answer with soumitra.bandi's explanation..but i must say its really a nice/tricky question...awesome dude!

the question is retarded

my answer would be
1
11
211
3211
53211

its the fibonacci series

1 = one
11 = one one
21 = two ones
1211 = one two one one
111221 = one one one two two ones

I get why the answer is that, but at the same time, 1, 21, 31, 41, 51... makes perfect sense! How is an interviewee suppose to know that they have to think contrary to common sense?

Since fibonacci nos. starts from 0, we need to clarify once with the interviewer that are we allowed to assume as if the series would have started with 0, then the sequence would be:

0
1
11
...

if this is the case then how you cn get 1 in the 2nd step unless you just assume again. May be that is why soumitra's soln is the answer. Though I like this fibonacci soln as well.

1-1
11-(1+1)=2
21-(2+1)=3
1211-(1+2+1+1)=5
111221-(1+1+1+2+2+1)=8
.........next term will be 13......
.........next term will be (8+13)21........

retards working for Bloomtard will ask these stupid questions... they don't show jack.. Man, I don't think I"m going to submit my resume to them anymore. They seem to grap stupid and not relevant questions out of their asses. Would Google ask something like this. geez. I been looking around bloomtard's questions and some of them are ridiculous and no indication of what the person can do.

This is one of them "Har har!" trolling types of questions.

You can fit a lot of nice simple functions on three points. So there are many perfectly valid different answers to this question.

The correct answer is: "YOU TELL ME! I can't read your mind, bro."
