We can see that the ratio between consecutive numbers is
[tex]\frac{-6}{-3}=\frac{-12}{-6}=\frac{-24}{-12}=2[/tex]this means that, the nex number is
[tex]\begin{gathered} -24\cdot2=-48 \\ \text{and next} \\ -48\cdot2=-96 \\ \text{and finally} \\ -96\cdot2=-192 \end{gathered}[/tex]Hence, the answer is -48, -96, -192
