A sequence of numbers begins with 12 and progresses geometrically. Each number is the previous number divided by 2. Which value can be used as the common ratio in an explicit formula that represents the sequence?

Each number is the previous number divided by 2
⇒ The ratio would be 1/2
The sequence starts with 12 and the sequence will be:
First Term = 12
Second Term = 12 ÷ 2 = 6
Third Tern = 6 ÷ 2 = 3
And so on ...
So the sequence would be : 12 , 6, 3, 3/2 , 3/4 ....
Answer: The ratio is 1/2

Thank you for asking this question. Here is your answer:
The common ratio is the current number divided by the previous. So the ratio is 1/2
The sequence is 12, 6, 3, 3/2, 3/4 ...
You can obtain any number multiplying the previous number times 1/2.
6 = 12 *(1/2)
3 = 6*(1/2)
3/2 = 3*(1/2)
