12 pts) Use Mathematical Induction to prove that an=n3+5n is divisible by 6 when ever n≥0. You may explicitly use without proof the fact that the product n(n+1) of consecutive integers n and n+1 is always even, that is, you must state where you use this fact in your proof.Write in complete sentences since this is an induction proof and not just a calculation. Hint:Look up Pascal’s triangle. (a) Verify the initial case n= 0. (b) State the induction hypothesis....

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...
