5. Consider the Josephus problem: in class, we looked at n elements in a circle and eliminated every second element until only one was left. The last element surviving this process was called the Josephus number. Instead of finding the last survivor, let I(n) be the element that survives second to last. To give a few small values, I(2) = 1, I(3) = 1, I(4) = 3, and I(5) = 5. Give a closed form expression for I(n) for any n ≥ 2.
