WebThe steps to prove a statement using mathematical induction are as follows: Step 1: Base Case Show that the statement holds for the smallest possible value of n. That is, show that the statement is true when n=1 or n=0 (depending on the problem). This step is important because it provides a starting point for the induction process. nick lachey house for sale
