Definition 1: Let x, y E Z. Then x is divisible by y if there exist an integer k such that x = ky. Definition 2: The product of two consecutive integers is always divisible by 2. For example, k2 + 3 and k² + 4 are two consecutive integers for all integers k. Hence, its product (k? + 3)(k² + 4)is divisible by 2. Part 1. Prove the following statements using the Principle of Mathematical Induction (PMI). 1. Let a + 1 be a real number. Prove that a + a? + a3 + ...+ a" = an+l=a for all integers n 2 1. a-1
