WebTo prove divisibility by induction, follow these steps: Show that the base case (where n=1) is divisible by the given value. Assume that the case of n=k is divisible by the given value. Use this assumption to prove that the case where n=k+1 is divisible by the given value. Conclude that by induction, the divisibility is true for all values of n. WebSo induction proofs consist of four things: the formula you want to prove, the base step (usually with n = 1), the assumption step (also called the induction hypothesis; either way, usually with n = k), and the induction step (with n = k + 1). But...

The induction hypothesis is the following: “Suppose that for some n > 2, A(k) is true for all k such that 2 ≤ k < n.” Assume the induction hypothesis and consider A(n). If n is a prime, then it is a product
