Answer:
Correct Answer: D
Step-by-step explanation:
Geometric Sequence
We can find each term of a geometric sequence if we have the general formula by replacing n for any integer number in the given domain. n must be an integer because it's the position where the term is located. For example, [tex]a_2[/tex] is the term located in position 2, so n cannot be irrational or decimal. The sequence provided is
[tex]\displaystyle y=\left( \frac{1}{2} \right )^n[/tex]
The variable n starts from 0 and has no limit, so the domain is a set of integers
[tex]\{0,1,2,3,4...\}[/tex]
[tex]\boxed{\text{Correct Answer: D}}[/tex]
