1. Use induction to prove that Summation with n terms where i=1 and Summation 3i 2 − 3i + 1 = n^3 for all n ≥ 1. 2. Let X be the set of all natural numbers x with the property that x = 4a + 13b for some natural numbers a and b. For example, 30 ∈ X since 30 = 4(1) + 13(2), but 5 ∈/ X since there’s no way to add 4’s and 13’s together to...
