An arithmetic sequence in algebra is a sequence of numbers where the difference between every two consecutive terms is the same. Generally, the arithmetic sequence is written as a, a+d, a+2d, a+3d, ..., where a is the first term and d is the common difference.

Feb 14, 2022 · An arithmetic sequence is a sequence where the difference between consecutive terms is constant. The difference between consecutive terms in an arithmetic sequence, a_{n}-a_{n-1}, is \(d\), the common difference , for \(n\) greater than or equal to two.
An arithmetic sequence is a sequence where consecutive terms are calculated by adding a constant value (positive or negative) to the previous term. We call this constant value the common difference (\ (d\)). For example, \ [\text {3}; \text {0}; -\text {3}; -\text {6}; -\text {9}; \ldots\]
