Example proof by strong induction

WebRewritten proof: By strong induction on n. Let P ( n) be the statement " n has a base- b representation." (Compare this to P ( n) in the successful proof above). We will prove P ( 0) and P ( n) assuming P ( k) for all k < n. To prove P ( 0), we must show that for all k with k ≤ 0, that k has a base b representation. WebNov 15, 2024 · Strong induction is another form of mathematical induction. In strong induction, we assume that the particular statement holds at all the steps from the base case to \(k^{th}\) step. Through this induction technique, we can prove that a propositional function, \(P(n)\) is true for all positive integers \(n\). Statement of Strong Induction: Let ...
