How to Use the AI Geometric Sequence Calculator

  1. Enter the First Term of the sequence.
  2. Input the Common Ratio between the terms.
  3. Specify the Term Number (n) you want to calculate.
  4. Click on 'Calculate' to view the Nth Term and Sum of n Terms.
  5. Review the results displayed on the screen.

How the Geometric Sequence Calculator Works

Nth Term = first_term * common_ratio^(n - 1)
Sum of n Terms = first_term * (common_ratio^n - 1) / (common_ratio - 1)

The Nth term of a geometric sequence is calculated using the formula nth_term = first_term * common_ratio^(n - 1). For example, if the first term is 2, the common ratio is 3, and n is 4, the Nth term will be 2 * 3^(4 - 1) = 54. The sum of the first n terms is calculated with sum = first_term * (common_ratio^n - 1) / (common_ratio - 1). Using the same values, the sum would be 2 * (3^4 - 1) / (3 - 1) = 80.

Frequently asked questions

What is a geometric sequence?

A geometric sequence is a series 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.

How do I find the Nth term?

To find the Nth term, you can use the formula nth_term = first_term * common_ratio^(n - 1). Input your values into the calculator for quick results.

What if the common ratio is negative?

The calculator can handle negative common ratios. The terms will alternate in sign depending on whether n is odd or even.

Can I use this for infinite sequences?

This tool calculates terms and sums for finite geometric sequences. For infinite sequences, different approaches are used.

Is this calculator free to use?

Yes, the Geometric Sequence Calculator is completely free to use, allowing you to perform calculations without any cost.
