WebJul 7, 2024 · The Second Principle of Mathematical Induction: A set of positive integers that has the property that for every integer \(k\), if it contains all the integers 1 through \(k\) then it contains \(k+1\) and if it contains 1 then it must be the set of all positive integers. More generally, a property concerning the positive integers that is true for \(n=1\), and that is … 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 ...
