It looks like you had some of the numbers correct, but you just labeled it and rounded it incorrectly, and the teacher gave you super partial credit for it.
For my work, I'm assuming that side A is opposite of angle A and side B is opposite of angle B, etc...
Answer:
B. All integers where n ≥ 1
Step-by-step explanation:
We are given the geometric sequence where a1 = 2 and the common ratio is 8.
Where a1 is the first term.
we have to find the domain for n.
The general formula for the geometric sequence is:
Clearly, n can take any integer value n≥1
Hence, the correct option is:
B. All integers where n ≥ 1
