WebProof by induction is a way of proving that a certain statement is true for every positive integer $n$. Proof by induction has four steps: Prove the base case: this means proving that the statement is true for the initial value, normally $n = 1$ or $n=0.$; Assume that the statement is true for the value $ n = k.$ This is called the inductive hypothesis.
