Answer:
I think the answer choices are incorrect. 7 1/2 in decimal form would be 7.5. Please correct me if I'm wrong.
Step-by-step explanation:
In the middle there are 13 units away.
Divide 6 by -1. Remember that -y is really -1y.
Answer:
The answer is 20^(n)
Step-by-step explanation:
From the problem, we know that
a^(3) = 30000 (1)
a^(5) = 12 000 000 (2)
If we divide (2) and (1)
a^(5) / a^(3) = a^(2)
a^(2) = 12 000 000/ 30 000 = 400
a = sqrt(400) = 20
The rule of the geometric sequence would be
20^(n)
Answer:
