Get A Piece of Paper, on the 1st line write a1
On the line underneath write 11
On the line underneath 21
Underneath 1211
Underneath 111221
What comes next??

312211.


EDIT: Want to know why or want to figure it out yourself?

Ah no, sure you might as well tell me now....

Ah sure, it's not really a standard number sequence. It goes like this.

The numeral 1 is just one one.
One one can be written as 11.
11 is actually two ones.
Two ones can be written as 21.
2 1 is one two and one one.
One one and one two is 1211.
1211 is one one, one two, and two ones.
One one, one two, and two ones is 111221.
111221 is three ones, two twos, and one one.
So the next number is 312211.
