Compute the sum
2(2 1/2) + 3(2 1/3) + 4(2 1/4) + 5(2 1/5) +. + 10(2 1/10)

2/15

Step-by-step explanation:Given the sequence An = {1, 3, 5, 7, 9},. (a) what is ... (a) The index of a3 is n = 3 so they're asking me for the third term, which is "5". ... To find the series sum, I'll be adding all the terms, like this: 2(0) + ... List the first four terms of the sequence {an} = {n2}, starting with n = 1. ... {12, 22, 32, 42}. = {1, 4, 9, 16} ... 2 – 4 + 6 – 8 + 10.
