Webb17 apr. 2024 · In a proof by mathematical induction, we “start with a first step” and then prove that we can always go from one step to the next step. We can use this same idea to define a sequence as well. We can think of a sequence as an infinite list of numbers that are indexed by the natural numbers (or some infinite subset of $\mathbb{N} \cup \{0\})$. WebbThe way I understand complete induction, as applied to the naturals at least, the inductive step consists of assuming that a given proposition p i is true for 1 ≤ i ≤ n, and from this deduce the truth of of p n + 1. However, I had thought that one always needed to check the base case ( i = 1 ).
