Mathematical induction in its simplest form may be stated thus: Suppose there is a set of propositions p0, p1, p2…which are so related that the truth of pn implies the truth of pn+1 then if p0 is true, it follows that all the other propositions of the set are true. For since p0 is true therefore p2 is true, therefore p2 is true, and so on as far as we please.
