WebbHence, by the principle of mathematical induction, P (n) is true for all natural numbers n. Answer: 2 n > n is true for all positive integers n. Example 3: Show that 10 2n-1 + 1 is divisible by 11 for all natural numbers. Solution: Assume P (n): 10 2n-1 + 1 is divisible by 11. Base Step: To prove P (1) is true. WebbFor all integers n, if 2n−11 is even then n is odd. This statement is true vacuously. For every integer n, 2n−11 = 2(n−6)+1 where n−6 is an integer, thus 2n−11 is odd and so cannot be even. Since the “if” part of the conditional never holds, the statement is true vacuously. 2. Prove or disprove the following statements:

In calculus, induction is a method of proving that a statement is true for all values of a variable within a certain range. This is done by showing that the statement is true for the first term in the range, and then using the principle of mathematical induction to show that it is also true for all subsequent terms.
