This is a video that showcases induction for a two-term recurrence: https://www.youtube.com/watch?v=0bkUe3bdISI

This is a video that showcases induction for a three-term recurrence: https://youtu.be/yBbKFSLHlFw?t=706 - you'll need to skip to about 12 minutes in.

I would go and watch a video/read a good textbook about it, but the general form of induction that I use as a framework is to write out the LHS and RHS and then:

1) Prove for n=1 (both sides)
2) Assume true for n=k (LHS)
3) Prove for n=k+1 by using your assumed LHS n=k
