Text: Use the principle of strong induction to prove that postage of n cents can be formed using just 4 cent and 7 cent stamps, for all n ≥ 18.
Added by Lori F.
Step 1
We can form 18 cents using three 4 cent stamps and one 6 cent stamp. Therefore, the base case holds. Step 2: Inductive hypothesis Assume that the statement is true for all values of k, where 18 ≤ k ≤ n. This is called the inductive hypothesis. Step 3: Inductive Show more…
