Answer:
The average rate of change form n = 1 to n = 3 is 3.
Step-by-step explanation:
n = 1 (1, 2)
n = 3 (3,8)
Rate of change: [tex]\frac{f(b)-f(a)}{b-a}[/tex]
[tex]\frac{f(b)-f(a)}{b-a}=\frac{8-2}{3-1} =\frac{6}{2} =3[/tex]
There the average rate of change form n = 1 to n = 3 is 3.
Hope this helps!
