Answer:
Graphs C and D show an arithmetic sequence.
Step-by-step explanation:
Arithmetic sequences have a common difference, meaning that the gap between each term in the sequence is always the same.
In Graphs A and B, the gap between terms seems to be changing. That tells us that they aren't arithmetic. Instead, those are geometric sequences.
Meanwhile, Graphs C and D appear to be straight, meaning that the gap between the terms is constant.
