1,5,9,13,17 is this an arithmetic sequence

We know that all adjacent terms in an arithmetic sequence differ by the same amount, and that amount is called the common difference. Here, we can observe the pairwise difference between the adjacent terms in the sequence:

So, we see that the difference is always 4 so it is an arithmetic sequence. In fact, the sequence is:
