1. The problem statement, all variables and given/known data Hi, there are two questions that I'm quite stuck with. 1.Find the number of terms in each of these geometric sequences. a) 1,-2,4......1024 b) 54,18,6....2/27 2. Relevant equations ar^n-1 3. The attempt at a solution 1. a) r= -2 1x-2^n-1 ? b) r= 2 54x2^n-1? I'm not familiar with having negative or dividing these sequences, however I understand the basics of dealing with a problem like this that is a positive and multiplication question.
