Prove induction regions

WebbThe principle of induction is a way of proving that P(n) is true for all integers n ≥ a. It works in two steps: (a) [Base case:] Prove that P(a) is true. (b) [Inductive step:] Assume that P(k) is true for some integer k ≥ a, and use this to prove that P(k +1) is true. Then we may conclude that P(n) is true for all integers n ≥ a. Webb10 jan. 2024 · Mathematical induction is a proof technique, not unlike direct proof or proof by contradiction or combinatorial proof. 3 You might or might not be familiar with these yet. We will consider these in Chapter 3. In other words, induction is a style of argument we use to convince ourselves and others that a mathematical statement is always true.
