WebJan 26, 2024 · In this video I give a proof by induction to show that 2^n is greater than n^2. Proofs with inequalities and induction take a lot of effort to learn and are very confusing … WebHere is one example of a proof using this variant of induction. Theorem. For every natural number n ≥ 5, 2n > n2. Proof. By induction on n. When n = 5, we have 2n = 32 > 25 = n2, as required. For the induction step, suppose n ≥ 5 and 2n > n2. Since n is greater than or equal to 5, we have 2n + 1 ≤ 3n ≤ n2, and so dictionary grove
