Answer:
2/3
Step-by-step explanation:
Given : A geometric sequence : 18, 12, 8, 16/3,…
Solution :
Each term is found by multiplying the previous term by a constant in a Geometric Sequence .
In a Geometric Sequence common ratio is denoted by r
for n = 2
⇒
⇒
for n = 3
⇒
⇒
⇒
Thus the common ratio 'r' = 2/3
