WebProve that 2 n>n for all positive integers n Easy Solution Verified by Toppr Let P(n):2 n>n When n=1,2 1>1.Hence P(1) is true. Assume that P(k) is true for any positive integer k,i.e., 2 k>k we shall now prove that P(k+1) is true whenever P(k) is true. Multiplying both sides of (1) by 2, we get 2.2 k>2k i.e., 2 k+1>2k k+k>k+1 ∴2 k+1>k+1 Web24 dec. 2024 · Solution 3. What you wrote in the second line is incorrect. To show that n ( n + 1) is even for all nonnegative integers n by mathematical induction, you want to show …
