Either n+1 is … WebMaking Induction Proofs Pretty All of our induction proofs will come in 5 easy(?) steps! 1. Define 𝑃(𝑛). State that your proof is by induction on 𝑛. 2. Base Case: Show 𝑃(0)i.e. show the base case 3. Inductive Hypothesis: Suppose 𝑃( )for an arbitrary . 5. Conclude by saying 𝑃𝑛is true for all 𝑛by the principle of induction.

WebProof by Strong Induction State that you are attempting to prove something by strong induction. State what your choice of P(n) is. Prove the base case: State what P(0) is, then prove it. Prove the inductive step: State that you assume for all 0 ≤ n' ≤ n, that P(n') is true. State what P(n + 1) 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 ... " - Strong induction string ab
