a.
To tell: Does the graph represent an arithmetic sequence? Explain.
a.

Answer to Problem 54E
Yes the graph represents the arithmetic sequence.
Explanation of Solution
Given information: The bar graph shows the cost of advertising in a magazine.
Calculation: From bar graph we get sequence is
Common difference is same.
Therefore the graph represents the arithmetic sequence.
