<span>2, 4, 8, 16, –32, 64, …
Common ratio = 4/2 = 2
16/8 = 2
But -32/16 = -2.
The ratio is not constant, hence it is not a geometric.
D. The sequence is not a geometric sequence.</span>
Let's plug the coordinate point values into the equation:

(1,3) is
x₁ and (3,1) is x₂
Begin to simplify within the parenthesis:

Square the two numbers:
Add the two to get:
Since 8 is not a square number, this is as far as we can simplify this. Hope this helps!
The person above me is incorrect.
