In strong induction, we assume that the particular statement holds at all the steps from the base case to k t h step. Through this induction technique, we can prove that a propositional function, P ( n) is true for all positive integers n.

WebConclusion: By the principle of strong induction, it follows that is true for all n 2Z +. Remarks: Number of base cases: Since the induction step involves the cases n = k and n = k 1, we can carry out this step only for values k 2 (for k = 1, k 1 would be 0 and out of range). This in turn forces us to include the cases n = 1 and n = 2 in the ...
