<em>A sequence of numbers whenever the difference of any two successive members of the sequence remains constant.</em>
The explicit equation of any arithmetic sequence can be written as follows:

So here we know:
- First term is 5
- Second term is 3

Finally, the explicit formula is:

Moreover, the domain is any natural number.
