Answer
The graph of a sequence is a discrete graph.
Work Step by Step
Let us say one has a sequence $\left\{ {{a}_{n}} \right\},n=1,2,3,...$
When we plot the points (x, ${{a}_{n}}$ ) on the graph.
We observe that the graph plotted is not continuous and discrete. Since the sequence contains all the discrete points, therefore the plot of the sequence must be a discrete plot.
