For example, in the sequence 3, 6, 12, 24, the common ratio is 2, because each number is double the one before it. A geometric sequence is a list 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.
Infinite Geometric Sequence Sum Formula and How to Calculate It
If the first term is denoted as a₁ and the common ratio as r, the nth term is calculated as aₙ = a₁ * r⁽ⁿ⁻¹⁾. Negative ratios create an alternating pattern of positive and negative terms, adding a dynamic oscillation to the progression.
The Mechanics of a Geometric Sequence To identify this pattern, you simply divide any term by the term before it. Recognizing this multiplicative relationship is key to solving problems involving these sequences.

This fundamental difference explains why populations can explode under ideal conditions or why debt can balloon under the weight of compounding interest. Explicit Formula and Calculation Mathematicians use an explicit formula to find any term in the sequence without listing all the previous ones.
