Conway's "look and say" sequence starts with a digit, a seed, which is used to describe the next term. With a seed of one, the first term is 1. You look at the first term 1 and say "one one", so the second term is 11. You look at the second term 11 and say "two ones", so the third term is 21, and so forth.
