Arithmetic Sequences

Arithmetic Sequences CK-12 Foundation arithmetic sequence A sequence such as 1, 5, 9, 13, 17 or 12, 7, 2, –3, –8, –13, –18 which has a constant difference between terms The first term is a1, the common difference is d arithmetic sequence Finding the number of terms in an arithmetic sequence might sound like a complex task, but it's actually pretty straightforward

arithmetic sequence If the first term of the sequence is a and the common difference is d, then the arithmetic sequence can be written as a, a+d, a+2d, a+3d, …, a+d, …
