Answer 5

Sav: I agree with kx2bay that your expression 8 · 4n – 1 is hard to read. Either draw it, or use Equation Editor. You don't want to make your potential helpers guess what you mean, do you?\[a _{n }=8*4^{n-1}\]

Answer 6

Sav: I encourage you to show your work. I do not respond to "It's C right?" questions.
