Answer:
is the common ratio
Step-by-step explanation:
Common ratio(r) states that the ratio of each term of a geometric sequence to the term preceding it.

Given the sequence:
225, 45, 9, .........
Here,


and so on...
Using definition to find r.

After solving we get;

Therefore, the common ratio is, 
Sin^2 (2x) = (1 - cos(4x))/2
---> sin^4 (2x) = (1/4)(1 - cos4x)^2 = (1/4)(1 - 2cos4x + cos^2 (4x)) and replace cos^2(4x) by (1/2)(1+cos(8x)) --->answer
