WebProblem 3. Show that 6 divides 8n −2n for every positive integer n. Solution. We will use induction. First we prove the base case n = 1, i.e. that 6 divides 81 −21 = 6; this is certainly true. Next assume that proposition holds for some positive integer k, i.e. 6 divides 8k −2k. Let’s examine 8k+1 −2k+1: 8k+1 −2k+1 = 8·8k −2·2k ... WebProof by strong induction: Case 2: (k+1) is composite. k+1 = a . b with 2 a b k By inductive hypothesis, a and b can be written as the product of primes. So, k+1 can be written as the product of primes, namely, those primes in the factorization of a and those in the factorization of b. We showed that P(k+1) is true. So, by strong induction n P ...

The proof by mathematical induction (simply known as induction) is a fundamental proof technique that is as important as the direct proof, proof by contraposition, and proof by contradiction.It is usually useful in proving that a statement is true for all the natural numbers \mathbb{N}.In this case, we are going to …
Web19 sep. 2024 · Solved Problems: Prove by Induction. Problem 1: Prove that 2 n + 1 < 2 n for all natural numbers n ≥ 3. Solution: Let P (n) denote the statement 2n+1<2 n. Base case: Note that 2.3+1 < 23. So P (3) is true. Induction hypothesis: Assume that P (k) is true for some k ≥ 3. So we have 2k+1<2k. WebAssume P(k) is true for some k∈ N, that is, 2×1+3×2+4×2 +5×2˜ +⋯+ k+1 2ˆ' =k2ˆ … 1 For P(k + 1), 2×1+3×2+4×2 +5×2˜ +⋯+ k+1 2ˆ' + k+2 2ˆ ˆ=k2ˆ + k+2 2 , by (1) ˆ= k+ k+2 2 = 2 k+1 2ˆ = k+1 2ˆ˙. ∴ P(k + 1) is true. By the Principle of Mathematical Induction, P(n) is true ∀ n ∈ N. 1. (f) Let P(n) be the ...
