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 2 + 4 + 8 + ⋯ + 2 12 . The sum can be written as, 2 + 4 + 8 + ⋯ + 2 12 = 2 + 2 ⋅ 2 + 2 ⋅ 2 2 + ⋯ + 2 ⋅ 2 11 = ∑ n = 1 12 ( 2 ⋅ 2 n − 1 ) Clearly, it is the sum of first 12 terms of a geometric sequence { a n } = { 2 ⋅ 2 n − 1 } with the first term a 1 = 2 and the common ratio r = 2
