Explanation Formula used: The nth term of a Geometric Sequence: “If a geometric sequence { a n } has first term a 1 and common ratio r , then the n th term is determined by the formula a n = a 1 r n − 1 r ≠ 0 .” Sum of the first n terms of a Geometric Sequence: “Let { a n } be a geometric sequence with first term a 1 and common ratio r , where r ≠ 0 , r ≠ 1 . The sum S n of the first n terms of { a n } is S n = a 1 ⋅ 1 − r n 1 − r where r ≠ 0 , r ≠ 1 .” Calculation: The given sum is 40 + 5 + 5 8 + ⋯ + 40 ( 1 8 ) 13 − 1 . The sum can be written as, 40 + 5 + 5 8 + ⋯ + 40 ( 1 8 ) 13 − 1 = 40 + 40 ( 1 8 ) + 40 ( 1 8 ) 2 + ⋯ + 40 ( 1 8 ) 13 − 1 = ∑ n = 1 13 ( 40 ( 1 8 ) n − 1 ) Clearly, it is the sum of first 13 terms of a geometric sequence { a n } = { 40 ( 1 8 ) n − 1 } with the first term a 1 = 40 and the common ratio r = 1 8
