For any n ≥ 1 1 + 7 + 19 + ... + (3( n1)( n2) + 1) + (3 n ( n1) + 1) = n 3 14. a For any n ≥ 1, prove that 2 n +2 does divide 3 2 n1. (only one of (x1),(x+1) can be divisible by four at the same time, if one is even both are even) 14. b For any n ≥ 1, prove that 2 n +3 does not divide 3 2 n1. (Easy ±rst case, use the last problem to build up to this one.) 15. Expand the ±rst 3 terms of (2 x + 3) 15 . 16.
