Observe that no intuition is gained here (but we know by now why this holds). 2 Proof by induction Assume that we want to prove a property of the integers P(n). A proof by induction proceeds as follows: WebHere is the general structure of a proof by mathematical induction: Induction Proof Structure Start by saying what the statement is that you want to prove: “Let P (n) P ( n) be the statement…” To prove that P (n) P ( n) is true for all n ≥0, n ≥ 0, you must prove two facts: Base case: Prove that P (0) P ( 0) is true.

By the induction hypothesis, the last two blocks required p − 1 and q − 1 fits, respectively. Adding in the last fit, we conclude that the total number of fits is: ( p − 1) + ( q − 1) + 1 = ( p + q) − 1 = ( k + 1) − 1 = k as desired.

WebProof by strong induction Step 1. Demonstrate the base case: This is where you verify that P (k_0) P (k0) is true. In most cases, k_0=1. k0 = 1. Step 2. Prove the inductive step: This is where you assume that all of P (k_0) P (k0), P (k_0+1), P (k_0+2), \ldots, P (k) P (k0 +1),P (k0 +2),…,P (k) are true (our inductive hypothesis).
