## Quick Answer

Calculate the nth term or sum of an arithmetic sequence. Enter the first term, common difference, and term number to see step-by-step math.

## Definition

An arithmetic sequence calculator is an educational utility that computes individual terms and cumulative sums of arithmetic progressions. It applies the formulas a_n = a_1 + (n-1)d and S_n = (n/2)(2a_1 + (n-1)d) to solve for any unknown parameter, generating a progression table of the first ten terms with step-by-step arithmetic explanations.

## How to Use

1. **Enter sequence parameters** — Input the first term (a₁), the common difference (d), and the term position (n).
2. **Choose calculation target** — Select whether you want to solve for the nth term (a_n) or the sum of the first n terms (S_n).
3. **Read results** — View the calculated values, mathematical step breakdown, and a sequence table of the first 10 terms.
