Tool Overview

The Online Arithmetic Sequence Term Generator generates a list of the terms of an arithmetic sequence according to the rules.

An arithmetic sequence is a common type of sequence. If, starting from the second term, the difference between each term and its preceding term equals the same constant, the sequence is called an arithmetic sequence, and this constant is called the common difference of the arithmetic sequence, commonly denoted by the letter d. For example: 1,3,5,7,9…… 1+2(n-1).

The general term formula of an arithmetic sequence is: a n = a 1 + (n-1)d

The sum of the first n terms formula is: S n = n(a 1 + a n )/2

Note: All n above are positive integers.
