WebJun 9, 2012 · I see induction as a means of establishing proof of some statement that holds for all natural numbers. This very notion implies that the process is not finite since the set of natural numbers is not finite. Consider the sum of natural numbers from 1 to N. Induction give a proff, while induction merely an alternative means to calculate the sum. Web2 Answers. Hint. Show that log ( k + 1) − log ( k) < ( k + 1) − k. log 2 ( k + 1) < log 2 ( 2 k) = log 2 2 + log 2 k = 1 + log 2 k < 1 + k. The first strict inequality holds whenever k + 1 < 2 k, …
