WebProof. We will prove this by inducting on n. Base case: Observe that 3 divides 50 1 = 0. Inductive step: Assume that the theorem holds for n = k 0. We will prove that theorem holds for n = k+1. By the inductive assumption, 52k 1 = 3‘ for some integer ‘. We wish to use this to show that the quantity 52k+2 1 is a multiple of 3.
