WebIt's going to be our first term-- it's going to be 5-- over 1 minus our common ratio. And our common ratio in this case is 3/5. So this is going to be equal to 5 over 2/5, which is the same thing as 5 times 5/2 which is 25/2 which is equal to …
WebThe common ratio is, r = (1/2) / 1 = (1/4) / (1/2) = (1/8) / (1/4) = ... = 1/2. Note that here r < 1. Using the geometric sequence formulas, the sum of n terms of a geometric sequence when r < 1 is, S n = a (1 - r n) / (1 - r) To find the sum of first 15 terms, substitute n = 15 on both sides.
