Goal: Prove some statement P[n] is true for all integers n ≥ 1 Step 1: State the base case P[1] and prove it. Step 2: State the inductive hypothesis P[m]. Step 3: Prove the inductive case P[m+1], assuming that the inductive hypothesis P[m] is true for some m ≥ n It’s often helpful to write P[m+1] in terms of something recognizable from P[m]The reason why this is called "strong induction" is that we use more statements in the inductive hypothesis. Let's write what we've learned till now a bit more formally. Proof by strong induction. Step 1. Demonstrate the base case: This is where you verify that \(P(k_0)\) is true.
