An arithmetic sequence can be recognized because it has a common difference between consecutive terms.
For example, if the common difference is 2, each term is found as the previous term plus 2.
If besides, we know the first term (for n = 1) is 0, then the sequence is:
0, 2, 4, 6, 8, ...
For n = 1, 2, 3, 4, 5, ... respectively
The graph that represent this sequence is D
Answer: Graph D
