(from Wikipedia: Collatz Conjecture )
The 3x+1 problem is a conjecture in mathematics which can be summarized as follows:
Take any positive integer n. If n is even, divide it by 2 to get n / 2. If n is odd, multiply it by 3 and add 1 to obtain 3n + 1. Repeat the process indefinitely. The conjecture is that no matter what number you start with, you will always eventually reach 1.
