first two years of college and save thousands off your degree. credit by exam that is accepted by over 1,500 colleges and universities. Proof: By induction on n \in N. Consider the base case o, Given two natural numbers x and y such that x greater than y, prove that x mod y less than x/2, Working Scholars® Bringing Tuition-Free College to the Community, The second step is kind of tricky. . All rights reserved. About "Mathematical Induction Examples" Mathematical Induction Examples : Here we are going to see some mathematical induction problems with solutions. To unlock this lesson you must be a Member. Show that \sum_{k=1}^n k = \frac{n(n+1)}{2}, We are going to prove by induction that for all integers k 1, \sqrtk \frac1\sqrt{1} + \frac1\sqrt{2} + + \frac1\sqrt{k}. Let n = 4 and calculate 4 ! So, now the statement that we need to prove becomes (k)(k + 1) / 2 + (k + 1) = (k+1)((k + 1) + 1) / 2. . has thousands of articles about every succeed. Clearly this is true for k = 1. Solution to Problem 3: Statement P (n) is defined by 1 3 + 2 3 + 3 3 + ... + n 3 = n 2 (n + 1) 2 / 4STEP 1: We first show that p (1) is true.Left Side = 1 3 = 1Right Side = 1 2 (1 + 1) 2 / 4 = 1 hence p (1) is true. If the first domino falls, then all the other dominoes fall, too. Let's look at another problem.
