yes this is all one wuestion eith 4 other parts being a,b,c, and e

Exercise 1: Using the induction, verify that each equation is true for every positive integer n, n 2 1. a) 1* 2 + 2 * 3 + 3 * 4 + ... + n(n+1) = "h? - (n+1)(x+2) b) 1(1!) + 2(2!) + ... + n(n!) =(n+1)!- 1 c) 13 + 23 +33 + ... + n3 = _n(3n-1) e) 1+4+7+ ... + (3n - 2) =
