Answer 2

ok so what I'm GUESSING you do is replace n with numbers 1 through 10 and just solve them one by one

Answer 3

for example a(1) = 3(1) - 3
a = 3-3
a=0

Answer 4

that's the first one

Answer 5

I honestly don't know because I would have to solve all of them, but you get the gist of what you have to do, now all you have to do is solve them :) hope I helped.
