Natalia should use 3/2 as common ratio
Step-by-step explanation:
Common ratio is the ratio between consecutive terms of a geometric sequence
It is denoted by r
Given sequence is:
8, 12, 18, 27, ...
Here
[tex]a_1 = 8\\a_2 = 12\\a_3 = 18\\a_4 = 27[/tex]
So,
[tex]r = \frac{a_2}{a_1} = \frac{12}{8} = \frac{3}{2}\\r = \frac{a_3}{a_2} = \frac{18}{12} = \frac{3}{2}\\r = \frac{a_4}{a_3} = \frac{27}{18} = \frac{3}{2}[/tex]
Hence,
Natalia should use 3/2 as common ratio
