Problem 18. (1 point) 6 Consider the series 12 tr 7+1 a. The general formula for the sum of the first n terms is S b. The sum of a series is defined as the limit of the sequence of partial sums, which means 6 = lim (0)- = cọ trẻ tro 7-1 12 100 c. Select all true statements (there may be more than one correct answer): A. The series is a telescoping series (i.e., it is like a collapsible telescope). B. Most of the terms in each partial sum cancel out. C. The series is a p-series. D. The series converges. E. The series is a geometric series. Note: You can earn partial credit on this problem.
