Answer:
The common ratio is [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given sequence,
27, 9, 3, 1
Since,
[tex]\frac{9}{27}=\frac{3}{9}=\frac{1}{3}[/tex]
Hence, in the given sequence the ratio of a term to its previous term is [tex]\frac{1}{3}[/tex]
Therefore, we can say that,
The common ratio of the given sequence is [tex]\frac{1}{3}[/tex]
