WebJul 7, 2024 · To show that a statement q is true, follow these steps: Either find a result that states p ⇒ q, or prove that p ⇒ q is true. Show or verify that p is true. Conclude that q must be true. The logic is valid because if p ⇒ q is true and p is true, then q must be true.

Then we have 3n + 2 is odd, and n is even. The latter implies that n = 2k for some integer k, so that 3n + 2 = 3(2k) + 2 = 2(3k + 1). Thus, 3n + 2 is even.
