I'm not sure how to complete both of these parts. I tried answering the 2nd part but im unsure if it's correct.

For the following telescoping series, find a formula for the nth term of the sequence of partial sums {S, ). Then evaluate lim S, to obtain the value of the series or state n-09 that the series diverges. BW = 1 (5k - 3)(5k + 2) S, = Select the correct choice and fill in any answer boxes in your choice below. O A. 2 (5k - 3)(5k + 2) Simplify your answer.) O B. The series diverges
