Digit Sequence (Posted on 2005-06-28) Difficulty: 2 of 5
Find the rule and continue this sequence of digits:

1235813941213533488671216141383377554...

Is there a limit to the number of times in a row a digit can appear?

fibbonnacci to the rescue | Comment 15 of 16 |

The Fibbonacci sequence is defined by:

F1=1

F2=1

Fn=F(n-1)+F(n-2)

This is like the fibbonnacci sequence, except it's the concatenated version of it with 1 and 2 as the first numbers, so it's 1235813, and now that we've hit a 2 digit number, we add digit(n-2) and digit(n-3) for the next digits, and the next time we hit a 2 digit number, the next digits will be digit(n-3) and digit(n-4) etc.
