Sequence Calculator

Arithmetic and Geometric Patterns

Sequences describe ordered number patterns with a position number.

Arithmetic: an = a1 + (n - 1)d.

Understanding Sequences

1. What This Calculator Measures

A sequence is an ordered list of numbers that follows a pattern.

2. How the Calculation Works

The calculator uses arithmetic formulas for constant differences and geometric formulas for constant ratios.

3. Formula or Rule Used

arithmetic: an = a1 + (n - 1)d; geometric: an = a1 x r^(n - 1).
