Find infinite sum of geometric sequence
WebSo a geometric series, let's say it starts at 1, and then our common ratio is 1/2. So the common ratio is the number that we keep multiplying by. So 1 times 1/2 is 1/2, 1/2 times 1/2 is 1/4, 1/4 times 1/2 is 1/8, and we can …

WebThere is a well known formula for the sum to infinity of a geometric series with r < 1, namely: S ∞ = a 1 − r. In your case, a = 3 / 5 and r = − 1 / 5, and so it follows that: S ∞ = 3 / 5 1 + 1 / 5 = 1 2.
