How to determine a common ratio
WebThe nth term of a GP is an =128 a n = 128. The first term of the GP is a = 2 a = 2. The common ratio of the GP is r =2 r = 2. Now use the condition if the first and nth term of a GP are a and b respectively then, b =a ⋅rn−1 b = a ⋅ r n − 1, to calculate the total number of terms. WebThe formula to determine the sum of n terms of Geometric sequence is: Sn = a[(rn − 1) / (r − 1)]ifr ≠ 1. Where a is the first item, n is the number of terms, and r is the common ratio. …
