A common "Stefani Problem" involves proving identities of Fibonacci numbers, such as:

∑i=1nfi2=fnfn+1sum from i equals 1 to n of f sub i squared equals f sub n f sub n plus 1 end-sub Step-by-Step Induction Proof .The base case holds. Inductive Step: Assume the formula holds for . We must show it holds for stefani_problem_stefani_problem
