WebGeometric sequence To recall, an geometric sequence or geometric progression is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. Thus, the formula for the n-th term is where r is the common ratio. WebExplicit geometric sequences also have a formula for finding any term in a sequence. an = a1 r(n-1) an = the term in the sequence you are trying to find ( n represents the desired term number) a1 = the first term in the sequence r = the common ratio Example 1. What is the 15th term of the geometric sequence -9, 27, -81, … ? Solution:
