i know i have to find A and D using simultaneus equations my 1st one is

A+11d= 35

but i dont know how to write my second one, how do i write the 17th term being four times the 2nd term?

Well the second term is the first term plus the common difference.

So A + 16d = 2(A + d)

So A + 16d = 2(A + d)
wouldnt it be 4(A+D) because A+D = 2nd term, ?

Yep, it's just that I'm a bit blind and dumb and can't read properly.
