WebSection 2.5 Induction. Mathematical induction is a proof technique, not unlike direct proof or proof by contradiction or combinatorial proof. 3 In other words, induction is a style of argument we use to convince ourselves and others that a mathematical statement is always true. Many mathematical statements can be proved by simply explaining what they mean. WebProof. We will prove this by inducting on n. Base case: Observe that 3 divides 50 1 = 0. Inductive step: Assume that the theorem holds for n = k 0. We will prove that theorem holds for n = k+1. By the inductive assumption, 52k 1 = 3‘ for some integer ‘. We wish to use this to show that the quantity 52k+2 1 is a multiple of 3. free games pc open world https://groupe-visite.com

First and foremost, the proof is an argument. It contains sequence of statements, the last being the conclusion which follows from the previous statements. The argument is valid so the conclusion must be true if the premises are true.
