I got to that, but I'm not sure where to go from this stage. I might divide it but I am not permitted a calculator.

Could you also please show me how to solve $-n 2^{n-1}=192$? Thanks!

comment Finding degree of expression
Thanks! Just on two little parts, how would you solve $-n\cdot2^{n-1}=-192$ and how did you get $\frac{n!}{(n-1)!}(2a)^{n-1}=-n\cdot2^{n-1}a^{n-1}$?

Thanks for your clear answer! I understand the latter part, but can you please explain how A, B and C are also equal to it? I've just come out of high school in a poor district with sub-par math teaching and I'm trying to catch back up again.
