Answer:
D
Step-by-step explanation:
By looking at the terms, we can notice that each term is 4 times the previous term. This means the series is geometric and we can rule out options A and B because of this. We can find the first terms of both options C and D to get:
first term c: 4
first term d: 1
The first term of our series is one, so that must mean D is the answer.
