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. For example, in the sequence 3, 6, 12, 24, the common ratio is 2, because each number is double the one before it.

There is a specific formula to find the sum of the first n terms, which depends on whether the ratio is greater than or less than one. Real-World Applications The concept extends far beyond the classroom, modeling real-world phenomena where change happens by a constant percentage.
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⁾. Visualizing Growth and Decay When the common ratio is greater than 1, the sequence exhibits exponential growth, with numbers quickly becoming very large.

Recognizing this multiplicative relationship is key to solving problems involving these sequences. This consistent multiplier creates a pattern of rapid growth or decay, distinguishing it from the constant addition found in an arithmetic progression.
