Arithmetic and Geometric Sequence Calculator

About Arithmetic and Geometric Sequence Calculator

Arithmetic and Geometric Sequence Calculator helps you inspect three popular sequence families from a small set of inputs. It can preview the sequence, calculate the requested nth term, and compute the sum of the first n terms without writing the formulas by hand.

How To Use It

Choose the sequence type first, then enter the values needed for that pattern.

• Select Arithmetic, Geometric, or Fibonacci depending on the sequence you want to build.
• Enter the starting values plus the common difference, common ratio, or second starting number as needed.
• Set the nth position and click Calculate Sequence to view the preview, nth term, and total sum.
