You may see one or two sequence questions on the test but unlikely to see more. Difficulty levels can vary - this can be written as relatively easy questions or quite difficult / tricky ones.
Also, just FYI, the second formula you listed below is actually:
an^2 + bn + c
Generally, if you are going for a 750, you need to know everything, just in case. If you are going for a 700, you might want to know this. If you are shooting for under a 700, you should review it so you know the basics and can handle straightforward questions, but don't spend too much time on it.
