Arithmetic Sequence Calculator

An arithmetic sequence changes by the same common difference d from one term to the next. Formula: aₙ = a₁ + (n−1)d; Sₙ = n[2a₁ + (n−1)d] ÷ 2

Calculate an Arithmetic Sequence

An arithmetic sequence changes by the same common difference d from one term to the next.

Formula: aₙ = a₁ + (n−1)d; Sₙ = n[2a₁ + (n−1)d] ÷ 2

Write the inputs in the form required by the formula and check the result with a small reference case. For equations and statistics, make sure the selected convention matches the problem you are solving.

Substitute the same inputs into the displayed formula and compare the calculated value with the result shown by the tool.
