Full Idea

The principle of complete induction says suppose that for every number, if all the numbers less than it have a property, then so does it; it then follows that every number has the property.

Gist of Idea

Complete induction assumes for all numbers less than n, then also for n, and hence for all numbers

A Reaction

Complete induction is also known as 'strong' induction. Compare Idea 13358 for 'weak' or mathematical induction. The number sequence need have no first element.
