Statement: Start with any positive integer n. If n is even replace n by n/2; if n is odd replace n by 3n+1. Every such sequence eventually reaches 1 (equivalently, enters the cycle 4 -> 2 -> 1). If unsolved, report the best partial results and references. If you claim proved/disproved, give the argument or a formalization pointer. Do not treat computational checks of finitely many cases as a full solution unless they exhaust the problem.
