Mathematical Induction - Stanford University
WebbInduction basis: Show that the assertion A(1) holds. Induction step: For all positive integers n, show that A(n) implies A(n+1). 3. Standard Example: Sum of the First n Positive Integers (1/2) 4 For all n 1, we have P n k=1 k = n(n +1)/2 We prove this by induction. Let A(n) be the claimed equality.

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. how to help with dyslexia
