WebThis explains the need for a general proof which covers all values of n. Mathematical induction is one way of doing this. 1.2 What is proof by induction? One way of thinking about mathematical induction is to regard the statement we are trying to prove as not one proposition, but a whole sequence of propositions, one for each n. WebIn Example 2, it's hard to see how we could prove that factors into primes if the5 induction assumption were only about the single number preceding that is, if the5 induction assumption were merely that factors into primes. In the proof in5 " Example 2, we need to know, somehow, that and are products of primes and that's:;
