WebFind the sum of the first n terms of the GP. Solution: Let 'a' and 'r' be the first term and the common ratio of the given GP respectively. Then: a + ar + ar 2 = 16 ar 3 + ar 4 + ar 5 = 128 We can rewrite these equations as: a (1 + r + r 2) = 16 ar 3 (1 + r + r 2) = 128 Dividing the second equation by first, umass dayton prediction
