Problem number 14 of Project Euler gave a sequence.

n = n/2 if (n is even)

n = 3*n+1 (if n is odd)

It has been observed that all the numbers in this sequence do end up at 1, though this is yet to be proved! For example, if we consider the number 13, then the sequence pans out as

13 -> 40 -> 20 -> 10 -> 5 -> 16 -> 8 -> ...
