WebIn the given geometric sequence, The first term is, a = 1. The common ratio is, r = (1/4) / 1 = (1/16) / (1/4) = (1/64) / (1/16) = ... = 1/4. Note that here r < 1. Using the geometric sequence formulas, the sum of an infinite geometric sequence is, S_\infty = a / (1 - r) S_\infty = 1 / (1 - (1/4)) = 1 / (3/4) = 4/3.

WebNov 15, 2015 · So the sum of the first n terms of sequence is ; Sn = a(1 − rn) 1 − r. Now given you know r n and the sum you find a by re arranging. Additionally. If you re given the nth term then'. an = arn−1. You may often has to use both these equation to get to the answer. Answer link. WebMar 27, 2024 · an = a * rn - 1. where. n is the nth term. r is the common ratio. Let us see the steps that are given below to calculate the common ratio of the geometric sequence. Follow the guidelines carefully. First, give the values that are given in the problem. After that, apply the formula and substitute the values in it. Finally, you will get the answer. captive finance company meaning

Weba_n = a_1 r^ {n-1} an = a1rn−1. The above formula allows you to find the find the nth term of the geometric sequence. This means that in order to get the next element in the sequence we multiply the ratio r r by the previous element in the sequence. So then, the first element is a_1 a1, the next one is a_1 r a1r, the next one is a_1 r^2 a1r2 ... WebHow to use this calculator: Use the dropdown menu to choose the sequence you require.
