Answer:
The average rate of change is 3
Step-by-step explanation:
To find the average rate of change you need to find the slope of the starting point and the end point.
For n = 1 to n = 5, the end point is (5, 14) and the starting point is (1, 2).
The slope formula is:
[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Just find the slope of the starting point and the end point to find the average rate of change.
[tex]slope = \frac{14-2}{5-1} = \frac{12}{4} = 3[/tex]
The average rate of change is 3
