Step-by-step explanation:
If the lines are parallel, the slope of both of them are going to be the same. So if one line is 3, the other one will be too.
6a-(n-1)(3a) is the nth term
Expanding we get 6a-3an+3a=9a-3an=3a(3-n)
SOLUTION: nth term is 3a(3-n)
The same as the last question. B the second option.
