**Formula:** `An = A1 + (n - 1) * d`

The nth term of an arithmetic sequence is calculated using the formula: **An = A1 + (n - 1) * d**, where **An** represents the nth term of the sequence, **A1** is the first term, **n** is the position of the term in the sequence, and **d** is the common difference between terms. This formula is derived from the pattern that each term is the previous term plus a constant difference. Arithmetic sequences are used in various fields such as economics, computer science, and physics, to model linearly varying quantities.
