Answer 9

second term: 4

third term: 6

you're adding 2 each time

and you're starting with 2

------------------------------

so if you start with 2, and you add 2 say n times, then you're left with

2+2n

this only works if you start with n = 0, if you want to start with n = 1, you would have to subtract 2 to get 2+2n-2 = 2n+0 = 2n

So the general term is 2n
