I have forgotten how to do this. I recall the formula, but we went over it a week before the final so I was not paying 100% attention to learning it as I was to getting all the information I accumulated back and ready for the exams. something like
N(term)=N+1(something) and there are different ways to manipulate the formula, but I am guessing you only need basic sequence knowledge for the SAT. I am only concerned with getting a better SAT score right now.

won't give away answer so you guys have some fun without spoiling it
