Prove by induction the sum formula

The video tutorial explains the process of mathematical induction, focusing on proving a sum formula. It begins with an introduction to the induction process, followed by proving the base case. The instructor then details the inductive step, showing how to prove the formula for K+1. The tutorial concludes with an algebraic verification of the proof and a summary of its implications.
