Answer
Multiply the common ratio to get the next term to obtain:
$a_1=-\frac{1}{16}
\\a_2=\frac{1}{4}
\\a_3=-1
\\a_4=4
\\a_5=-16$
Work Step by Step
Multiply the common ratio to get the next term to obtain:
$a_1=-\frac{1}{16}
\\a_2=-\frac{1}{16}(-4) = \frac{4}{16} = \frac{1}{4}
\\a_3=\frac{1}{4}(-4)=-1
\\a_4=-1(-4)=4
\\a_5=4(-4) = -16$
