Puzzler: Any one know what the pattern is? 1,11,21,1211...?

Question

Can you find the 10th? The first 9 are as follows...

1
11
21
1211
111221
312211
13112221
1113213211
31131211131221

Answer 1

It is a code you have to break (and as such really belongs in Puzzles not in Mathematics) ...

the next 3 lines are:

13211311123113112211
11131221133112132113212221
3113112221232112111312211312113211

the way to read it is to read it aloud in pairs of digits, with the first in each pair being an adjective ("how many do I see?") and the second being a noun ("what do I see?"),

13211311123113112211
which you READ as:

(I see) one "1", one "3", one "2", two "1"s, one "3", three "1"s, one "2", one "3", two "1"s, one "3", two "1"s, two "2"s and two "1"s

and WRITE as:

11 13 12 21 13 31 12 13 21 13 21 22 21
without any gaps as they rather give the game away ...

Each line then literally (to those in the know)describes the line above.

Answer 2

The next line is
13211311123113112211

It means that in the preceding line there is 1 3, 2 1s,1 3,1 1,1 2,3 1s,1 3,1 1,2 2s, and 1 1

Answer 3

Um i think 12 n. on the f. of a c. is 12 numbers on the face of a clock but thats a complete guess

Answer 4

This is a descriptive pattern, i.e. the next number in the series describes in words what the previous number was:
11 means the prior number was "one one"
21 means the prior number was "two ones"
1211 means the prior number was "one two, and one one"
... and so on ...
the number following the last number would be, in words,
"one three, two ones, one three, one one, one two, three ones, one three, one one, two twos, and one one."
or
13211311123113112211

Hope that is right!

Answer 5

I believe the next line would be:
13211311123113112211

Each line describes the line before it. SWEET riddle.

Answer 6

I agree, this doesn't really belong in math. But I enjoyed it anyway :)
