# Arithmetic Progression

An arithmetic progression is a sequence where each term differs from its neighbors by a constant value. Thus, $$1, 4, 7, 10, 13, \dots$$ is an arithmetic progression with a common difference of $$3$$.

If the initial term of an arithmetic progression is given by $$a_1$$ and the common difference by $$d$$, then the general term is:

$a_n = a_1 + (n-1)d .$
