Answer: Choice C
Explanation:
Focus on the y coordinates. They are: 6, 3, 1.5, 0.75
Divide each by their previous term
- 3/6 = 0.5
- 1.5/3 = 0.5
- 0.75/1.5 = 0.5
We have a common ratio of r = 0.5
This proves we have a geometric sequence.
The starting term is a = 6
The nth term is [tex]a_n = a(r)^{n-1} = 6(0.5)^{n-1}[/tex] which is likely what choice C is showing. Though choice C should be written as 6(0.5)^(n-1)
