I've tried soooo many times on this question, but I just can't get it! It's due later today, so if someone would please explain to me what I'm supposed to do. I know what to do, but I'm doing something wrong, but I don't know what. I need to write a recursive and explicit formula for the sequence -16, 4, -1, 1/4, -1/16, 1/64 It is a geometric sequence.
