The common ratio of a geometric progression is determined by dividing one term by the previous one. Hence, in the geometric sequence shown in the question the common ration is derived as;


\begin{gathered} r=(24)/(4) \\ r=6 \\ \text{Also,} \\ r=(144)/(24) \\ r=6 \end{gathered}

The common ratio is 6, that is option C
