Jan 22, 2024 · Remember these properties to solve any arithmetic sequence problem effectively! Calculating Terms in an Arithmetic Sequence. In an arithmetic sequence, each term after the first is found by adding a constant, known as the common difference ( d ), to the previous term. I find that a clear understanding of the formula helps immensely:
