What is the Arithmetic Sequence Calculator?
An arithmetic sequence adds the same number (the common difference d) each time, like 5, 8, 11, 14. Enter the first term, d and n to get the nth term, the sum of the first n terms and the list of terms.
How to use the Arithmetic Sequence Calculator
- Enter a₁, d and n.
- Read aₙ, Sₙ and the listed terms.
What is the formula for the nth term?
aₙ = a₁ + (n - 1)d, and the sum is Sₙ = n/2 × (a₁ + aₙ).
This Arithmetic Sequence Calculator is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
