1:38 Aa Section 3.1 . Natural Numbers and Induction 109 (b) The principle of mathematical induction enables us to prove that a statement is true for all natural numbers without directly verifying it for cach number. 2. Mark each statement True or False. Justify each answer. (a) A proof using mathematical induction consists of two parts: establishing the basis for induction and verifying the induction hypothesis. (b) Suppose n is a natural number greater than 1. To prove P(k) is true for all k 2 m, we must first show that P(k) is false for all k such that 1sk<m. *3.
