Answer:
[tex]\begin{gathered} \text{ Geometric Sequence} \\ 4 \end{gathered}[/tex]Explanation:
Here, we want to check if the given sequence is geometric or arithmetic
if the sequence is arithmetic, there would be a common difference. If the sequence is geometric, there would be a common ratio
If there is a common ratio, if we divided the succeeding by the preceding term, we get a common ratio
Mathematically:
[tex]\frac{12}{3}\text{ = }\frac{48}{12}\text{ = 4}[/tex]Thus, the sequence is a geometric sequence while the common ratio is 4
