A) To find the sum Sf. 72-3 First, write the partial sum: SN = N+2 Thus the value of the sum is 1 (n + 2)(n+3) Slim Sy= N a = B) To find the sum S = 1 (n+2)(n+3) (3)" Find the first term (a) and the common ratio (r) for the geometric series: P =. (Use variable I.) Determine whether it is convergent or divergent: ? Then the value of the sum is S = (Write "DNE" if diverges.)
