Answer:
Common ratio of the geometric sequence {0.45, 0.9, 1.8, ...} is :
2
Step-by-step explanation:
If the nth term of the geometric sequence is A(n) then, the common ratio is given by:
A(n+1)/A(n)
Here, we are given a geometric sequence:
{0.45, 0.9, 1.8, ...}
A(3)/A(2) will give us the common ratio
[tex]\dfrac{A(3)}{A(2)}=\dfrac{1.8}{0.9}=2[/tex]
Hence, common ratio of the geometric sequence {0.45, 0.9, 1.8, ...} is :
2
