Geometric Sequence Formula ChiliMath
WebThe terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. For instance, if the first term of a geometric sequence is a1 = −2 a 1 = − 2 and the common ratio is r= 4 r = 4, we can find subsequent terms by multiplying −2⋅4 − 2 ⋅ 4 to get −8 − 8 then multiplying ... 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.
