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.
