Learn to use induction to prove the sum formula of a series

The video tutorial explains the process of proving a sum formula by mathematical induction. It begins with verifying the formula for the first term and then moves on to the inductive step, where the formula is rewritten for a general term K. The tutorial demonstrates how to simplify expressions and complete the proof by showing that the formula holds for K+1. The conclusion confirms the validity of the formula for all terms.
