Question 1

What is a Geometric Sequence Calculator?

Accepted Answer

A geometric sequence has each term as a constant multiple (common ratio r) of the previous term. Geometric sequences model exponential growth, compound interest, and population dynamics.

Question 2

How does the Geometric Sequence Calculator work?

Accepted Answer

aₙ = a₁ × rⁿ⁻¹ Then: Sum of n terms: Sₙ = a₁(1−rⁿ)/(1−r) Then: Sum to infinity (|r|<1): S∞ = a₁/(1−r) Then: Ratio r = aₙ/aₙ₋₁.

Question 3

Can you give an example of how to use the Geometric Sequence Calculator?

Accepted Answer

Example: Input a₁ = 2, r = 3, 5 terms gives a result of 2, 6, 18, 54, 162 — Sum = 242.

Question 4

Is the Geometric Sequence Calculator free to use?
