The general form of ANY geometric sequence is where "n" starts at 1 (the formula is slightly different if you start at different "n" values)



Start with the given equation.


Plug in and (these values are given)


Plug in (for the 7th term)


Subtract


Raise -4 to the 6th power to get 4,096


Multiply



So the 7th term is -12,288 which means that the answer is D)
