WebbInduction is when you prove the validity of a statement for a series of instances/trials. You prove it for the first instance i = 1, then assume it's true for an arbitrary instance i = n. After that, you have to prove that the next arbitrary instance i = n + 1. If successful, this completes the proof. Say you want to prove that i 2 > 2*i for i ...
