Answer:
d
Step-by-step explanation:
If the sequence is geometric then a common ratio r will exist between consecutive terms.
[tex]\frac{3}{12}[/tex] ÷ 1 = [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]
[tex]\frac{3}{48}[/tex] ÷ [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]
[tex]\frac{3}{192}[/tex] ÷ [tex]\frac{3}{48}[/tex] = [tex]\frac{1}{4}[/tex]
[tex]\frac{3}{768}[/tex] ÷ [tex]\frac{3}{192}[/tex] = [tex]\frac{1}{4}[/tex]
A common ratio of r = [tex]\frac{1}{4}[/tex]
Hence sequence is geometric
