Guest Posted September 15, 2007 Report Share Posted September 15, 2007 Here's a number sequence puzzle I saw in a magazine once: 1, 11, 21, 1211, ?? 111221, 312211, 13112221, 1113213211, 31131211131221.... The next number in the sequence describes the numerals before it, starting with 1. The next number is 11 or "1 one", 21 or "2 ones", 1211 or "1 two, 1 one", then 111221 or "1 one, 1 two, 2 ones."
