C. Prove the following claim, using proof by induction. Show your work. Let d be the day you were born plus 7 (e.g., if you were born on March 24, d = 24 + 7). If a = 2d + 1 and b = d + 1, then an – b is divisible by d for all natural numbers n.

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...

Please be able to follow the COMMENT Use induction proof to prove that For all positive integers n we have the inequality n<=2^n here is the step: base step: P(1)= 1<=2^1 inductive step: k+1<= 2^(k)+1 <= 2^(k)+k (since k>=1) <= 2^(k)+2^(k) = 2X2^(k) =2^(k+1) i don't understand why 1 can be replaced by k and i don't know why since k>=1
