WebThe 3n+1 problem can be stated in terms of a function on the positive integers: C (n) = n=2 if n is even, and C (n) = 3n + 1 if n is odd. The problem examines the iterations of this function and asks how these iterations behave. Specifically it asks if the starting point is important or if every starting point eventually reaches the number one.
