Answer:
This is an geometric sequence because the common ratio is -2.
Step-by-step explanation:
-2*-2=4
4*-2=-8
-8*-2=16
So, as we are seeing that the common ratio is -2, so this is an geometric sequence.
Answer:
g = ±2h
Step-by-step explanation:
4g^2 -1= 16h^2 -1
Add 1 to each side
4g^2 -1+1= 16h^2 -1+1
4g^2 = 16h^2
Divide each side by 4
4/4g^2 = 16/4h^2
g^2 = 4 h^2
Take the square root of each side
sqrt(g^2) = ±sqrt(4h^2)
g = ±sqrt(4h^2)
g = ±2h
