hello

we simply need to check if the sequence given has a common ratio or a common difference and what is the value


-3,-6,-12,-24

let's check if the sequence has a common ratio

to do this, let's pick two consecutive terms and check if the value corresponds


\begin{gathered} d=(-6)/(-3)=22 \\ d=(-12)/(-6)=2 \\ d=(-24)/(-12)=2 \end{gathered}

from the calculation above, the value of the common ratio is 2 and this corresponds to the first option
