1. In the first 2 problems, we are going to prove that induction and strong induction are actually equivalent. Let \( P(n) \) be a statement for \( n \geq 1 \). Suppose- \( P(1) \) is true;- for all \( k \geq 1 \), if \( P(k) \) is true, then \( P(k+1) \) is true.Prove by **strong induction** that \( P(n) \) is true for all \( n \geq 1 \).

In the first 2 problems, we are going to prove that induction and strong induction are actually equivalent. Let P(n) be a statement for n ≥ 1. Suppose • P(1) is true; ● for all k ≥ 1, if P(k) is true, then P(k + 1) is true. Prove by strong induction that P(n) is true for all n ≥ 1.
