WebInduction Step: Now F n = F n−1 +F n−2 = X(n−1)+X(n−2) (because S n−1 and S n−2 are both true), etc. If you are using S n−1 and S n−2 to prove T(n), then you better prove the base case for S 0 and S 1 in order to prove S 2. Else you have shown S 0 is true, but have no way to prove S 1 using the above proof—S 0 is not a base ... WebSep 19, 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. Induction step: To show P (k+1) is true. Now, 2 (k+1)1
WebTheorem 1. If n is a natural number, then 1 2+2 3+3 4+4 5+ +n(n+1) = n(n+1)(n+2) 3: Proof. We will prove this by induction. Base Case: Let n = 1. Then the left side is 1 2 = 2 and the right side is 1 2 3 3 = 2. Inductive Step: Let N > 1. Assume that the theorem holds for n < N.
