WebJul 7, 2024 · Theorem 3.4. 1: Principle of Mathematical Induction. If S ⊆ N such that. 1 ∈ S, and. k ∈ S ⇒ k + 1 ∈ S, then S = N. Remark. Although we cannot provide a satisfactory … WebThus, P(k + 1) is true whenever P(k) is true. So, by the principle of mathematical induction P(n) is true for all natural numbers n. Problem 2 : Use induction to prove that 10 n + 3 × 4 n+2 + 5, is divisible by 9, for all natural numbers n. Solution : Step 1 : n = 1 we have. P(1) ; 10 + 3 ⋅ 64 + 5 = 207 = 9 ⋅ 23. Which is divisible by 9 .
