Assignment - Solve the problems and write the solution in LaTeX:
1. For every integer n ∈ N, it follows that 12 + 22 + 32 + 42 + · · · + n2 = (n(n+1)(2n+1))/6.
2. If n ∈ N, then 1·2 + 2·3 + 3·4 + 4.5+ · · · + n(n+1) = (n(n+1)(n+2))/3.
3. For every natural number n, it follows that i=1∑n(8i - 5) = 4n2 - n.
4. If n ∈ N, then 1/2! + 2/3! + 3/4! + · · · + n/(n+1)! = 1 - 1/(n+1)! .
5. For any integer n ≥ 0, it follows that 3|(52n - 1).
