Webb12 jan. 2024 · Last week we looked at examples of induction proofs: some sums of series and a couple divisibility proofs. This time, I want to do a couple inequality proofs, and a couple more series, in part to show more of the variety of ways the details of an inductive proof can be handled. (1 + x)^n ≥ (1 + nx) Our first question is from 2001: WebbThis short document is an example of an induction proof. Our goal is to rigorously prove something we observed experimentally in class, that every fth Fibonacci number is a multiple of 5. As usual in mathematics, we have to start by carefully de ning the objects we are studying. De nition. The sequence of Fibonacci numbers, F 0;F 1;F 2;:::, are de-
