The two simplest sequences to work with are arithmetic and geometric sequences. An arithmetic sequence goes from one term to the next by always adding (or subtracting) the same value. For instance, 2, 5, 8, 11, 14,... is arithmetic, because each step adds three; and 7, 3, −1,...

Arithmetic Sequence Suppose that a, b and c is an arithmetic sequence, and a>b>c, then a-b=b-c. They have a common difference, and let the common difference be x, then x=a-b=b-c. For example, 1, 2 and 3 is an arithmetic sequence, and their common difference is 2-1 as we...
