For each positive integer n, we consider the following sequence of numbers F(n), F(nF(n)), F(nF(nF(n))), ⋯, where F(n) is the nth Fibonacci number defined in the usual way. Let Gk(n) be the kth term of this sequence. We prove that F(n)k || Gk(n) for all positive integers k and n with n > 3. For t...
