Let P(n) denote the propositional function 2n + 1 is an even integer with domain of discourse the positive integers. (i) Show that for any n €Z±, P(n) ⇒ P(n + 1). (You may assume all properties of even integers) (ii) Show that Vn ~P(n) is true ((n²+ n) is even for each positive integer n). Precisely explain why this does not contradict the Principle of Mathematical Induction.

Question
Let \( P(n) \) denote the propositional function \( 2n + 1 \) is an even integer with domain of discourse the positive integers. (i) Show that for any \( n \in \mathbb{Z}_+ \), \( P(n) \implies P(n + 1) \). (You may assume all properties of even integers) (ii) Show that \( \forall n \sim P(n) \) is true (\((n^2 + n)\) is even for each positive integer \( n \)). Precisely explain why this does not contradict the Principle of Mathematical Induction.
