To prove that \( a_n = 2^n + 3^n \) for all \( n \in \mathbb{Z}^+ \) using mathematical induction, we will follow the three steps of induction: base case, induction hypothesis, and induction step. ### Step 1: Base Case We need to verify the statement for the smallest positive integer, \( n = 0 \) and \( n = 1 \). - For \( n = 0 \): \[ a_0 = 2 ...
