so for the first term, you plug in n = 1 into the formula above, for the second plug in n = 2, etc
now this one is a little harder, but the answer to the last question helps us out. The first term of the corresponding sequence is , the second term is , the third term is and so on.b) Determine the eighth term of the corresponding sequence.
questions: why is that? do you know the difference between a sequence and a series? can you do the question now that you know all this information?
if you can't use LaTex, use "^" to represent powers. so you would type S_N = 3n^2 - n*meant to be n squared
