If you add the digits in the sequence you get the Fibonacci sequence. [1 = 1, 11 = 2, 21 = 3, 1211 = 5, 111221 = 8] => [1,2,3,5,8] I'm not sure if there being

If you add the digits in the sequence you get the Fibonacci sequence. [1 = 1, 11 = 2, 21 = 3, 1211 = 5, 111221 = 8] => [1,2,3,5,8] I'm not sure if there being multiple "correct" answers makes me like the question or hate it. The Fibonacci sequence seems a bit more obvious though than the "look and say" answer.
