The common ratio tells you by which factor every successive term will be with respect to the preceding term so you have:

-2(-1/4)(-1/4)(-1/4)

1/2, -1/8, 1/32

[tex]a_1=-2\\ a_2=-2\cdot\left(-\dfrac{1}{4}\right)=\dfrac{1}{2}\\ a_3=-2\cdot\left(-\dfrac{1}{4}\right)^2=-\dfrac{1}{8}\\ a_4=-2\cdot\left(-\dfrac{1}{4}\right)^3=\dfrac{1}{32}[/tex]
