What Is an Arithmetic Sequence?
An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant. This constant difference is called the common difference.
How is it calculated?
How Is It Calculated?
aₙ = a₁ + (n−1) × d
Sum: Sₙ = n × (a₁ + aₙ) ÷ 2
- Enter the first term, the common difference and the number of terms.
Frequently Asked Questions
Can the common difference be negative?
Yes; with a negative common difference the sequence decreases.
