I'm not sure what to do

1 pts Question 7 Let at =f(k), where f is a continuous, positive, and decreasing function on [n, co ), and suppose that Zat * =1 is convergent. Defining R. = S-Sm, where S = E an and Sn = Z ax, we have that n=1 *= 1 f(x)dox SR., S f(x)dx. Find the maximum error if the sum of the series 4 n + 1 is approximated by n =1 n SAO 0.0250 0.0006 0.1000 0.0025
