You have to multiply 1/4 by something so you can get to the number that is telling you to draw.
If a sequence is arithmetic, it will be linear. This does not appear to be a linear graph.
Therefore, I would conclude that it is not arithmetic.
Another way to tell is if the y - values have a common difference for consecutive x values.
For example, from term 1 to term 2 the difference is 5 but from term 2 to term 3 clearly the difference is not 5
