Consider the series n=0 a. Find the general formula for the sum of the first k terms. Your answer should be in terms of k. Sk = n=0 4 5n b. The sum of a series is defined as the limit of the sequence of partial sums, which means lim k→∞ = c. Select all true statements (there may be more than one correct answer): A. The series is a p-series. B. The series is a telescoping series (i.e., it is like a collapsible telescope). C. The series converges. D. The series is a geometric series.
