Answer:
Option D is correct.
Explicit formula for the geometric sequence is, 
Step-by-step explanation:
Geometric sequence states that a sequence of numbers in which the ratio between consecutive terms is constant,
we can write a formula for the nth geometric sequence in the form of:
.....[1] where
is the first term and r is the common ratio between successive term.
Given the sequence: 64, 32, 16 , 8......
Here, first term (
) = 64.
Common ratio(r) = 0.5
Since,

,
......
Substitute the value of a and r in [1] we get;

therefore, the explicit formula for the geometric sequence is,

Answer:
D
Step-by-step explanation:
use the formula for point slope form, since all of your choices are in that form : y-y1=m(x-x1) (m is the slope)
we're given that m=2 and the point is (2,9)
Substitute into the equation
y-9=2(x-2)
That means that the answer is D
