Just have a look at a similar problem and apply the same approach to your problem. We aren't going to do this Q for you.

One example can be seen here by a simple and quick youtube search on nth term of a quadratic sequence:

The first differences are 5, 15, 25, ...

And the second differences are 10, 10, ...

The second difference is constant which means this is a quadratic sequence.

Have you ever found nth terms of quadratic sequence before? If you have, please have a go and post all your working if you get stuck. If you haven't then I recommend watching a video e.g. this one.
