WebInductive step: Using the inductive hypothesis, prove that the formula for the series is true for the next term, n+1. Conclusion: Since the base case and the inductive step are both true, it follows that the formula for the series is true for all terms. WebInduction Step: Now we will prove that P (k+1) is true. To prove: 2 k+1 > k + 1 Consider 2 k+1 = 2.2 k > 2k [Using (1)] = k + k > k + 1 [Because any natural number other than 1 is greater than 1.] ⇒ P (n) is true for n = k+1 Hence, by the principle of mathematical induction, P (n) is true for all natural numbers n.
