Answer
The graph shown does not represent an arithmetic sequence.
Work Step by Step
The ordered pairs are $(1,2), (2,4),(3,7)$ and $(4,11)$.
The difference between first term and second term is $4-2=2$.
The difference between second term and third term is $7-4=3$.
Consecutive terms does not have a common difference. So, the given graph does not represent an arithmetic sequence.
