What is a geometric sequence?

Back

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

What is the common ratio in a geometric sequence?

Back

The common ratio is the factor by which we multiply each term to get the next term in a geometric sequence.

What is the formula for the nth term of a geometric sequence?

Back

The nth term can be calculated using the formula a_n = a_1 * r^(n-1), where a_1 is the first term and r is the common ratio.
