WebThe hypothesis in the induction step, that the statement holds for a particular n, is called the induction hypothesis or inductive hypothesis. To prove the induction step, one assumes the induction hypothesis for n … WebConclusion: By weak induction, the claim follows. Weak vs. Strong Induction The difference between these two types of inductions appears in the inductive hypothesis. In weak induction, we only assume that our claim holds at the k-th step, whereas in strong induction we assume that it holds at all steps from the base case to the k-th step.

WebStrong Induction To prove that P(n) is true for all positive integers n, where P(n) is a propositional function, complete two steps: Basis Step: Verify that the proposition P(1) is true. Inductive Step: Show the conditional statement [P(1)^P(2)^^ P(k)] !P(k+1) is true for all positive integers k. Generalizing Strong Induction WebProve the statement that n cents of postage can be formed with just 4-cent and 11-cent stamps using strong induction, where n ≥ 30. Let P(n) be the statement that we can form n cents of postage using just 4-cent and 11-cent stamps. To prove that P(n) is true for all n ≥ 30, identify the proper basis step used in strong induction.
