You can put this solution on YOUR website! 1, 11, 21, 1211, 111221
:
This is the "say what you see" sequence
:
The seed is 1 and all terms end in 1
:
you get 11 from 1 by saying one 1, i.e. 11
:
you get 21 from 11 by saying two 1's, i.e. 21
:
*********************************
therefore the next term is 312211
