0 Guest Posted July 3, 2011 Report Share Posted July 3, 2011 1113213211. This is because there is one 1, then one 3, then two 1s, then three 2s and then one 1. There can never be any number higher than 3 unless you start with it because there is no way to get 4 numbers in a row; you can't have one 1 and one 1 so there will be four 1s because it will just be two 1s. If you start with 22 the sequance will never change. My friend told me this. Quote Link to comment Share on other sites More sharing options...
