Find a formula for the general term {eq}a_n {/eq} of the sequence {eq}\{ 2, 7, 12, 17, \cdots \} {/eq}.

Question:

Arithmetic Progression:

An arithmetic progression is a sequence of real numbers such that from one term we pass to the next adding always the same constant value.

The general term of this type of sequence can be written as, {eq}{a_n} = {a_1} + \left( {n - 1} \right)d. {/eq}
