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.
In a certain sequence where the numbers are increasing, the difference between consecutive terms is always the same. If the fourth term in the sequence is 19 and the eleventh term is 47, what is the first term in the sequence?
won't give away answer so you guys have some fun without spoiling it
