Answer 5

it would help if there was some sort of non mind reading game that we could play like ... what is it you need from this?

Answer 6

I dont know D:

Answer 7

LMAO o I found it: What is a rule for the nth term of the arithmetic sequence with a10 = 22 and common difference d = 3?

Answer 8

A{n} = A{n-1} + 3 ; where A{0} = 8 is the best I can figure for it

Answer 9

(What I said not you)

Answer 10

common difference of 3 , ten times = 30; 30 + A{0} = 22

A{0} = 22-30 = -8

A{n} = -8 +3n :)
