Question

the nth term of a geometric sequence can be calculated using the formula $a_n = a_1 \cdot r^{n - 1}$, where $r$ stands for the .

Explanation:

In a geometric sequence, the formula \(a_n = a_1\cdot r^{n - 1}\) is used to find the \(n\)-th term. Here, \(a_1\) is the first term, \(n\) is the term number, and \(r\) represents the common ratio, which is the constant factor by which each term is multiplied to get the next term in the sequence.

Answer:

common ratio
