WebProof by Induction Suppose that you want to prove that some property P(n) holds of all natural numbers. To do so: Prove that P(0) is true. – This is called the basis or the base case. Prove that for all n ∈ ℕ, that if P(n) is true, then P(n + 1) is true as well. – This is called the inductive step. – P(n) is called the inductive hypothesis.
