Answer:
there is not enough information to solve
Step-by-step explanation:
You need two ordered pairs to calculate the average rate of change.
Let's say the value of the function at n = 1 is a, and the value of the function at n = 3 is b, then the average rate of change from n = 1 to n = 3 is
(b - a)/(3 - 1) = (b - a)/2

Answer:
8/3 or 2 2/3
Step-by-step explanation:
We do sums and differences of fractions by giving them a common denominator, then finding the sum or difference of the numerators. Here, you can reduce the first fraction to 10/3, so it will have the same denominator as the second fraction.
Now, you have ...
___
If you're really stumped, you can have your calculator do it.
Here, make them all powers. You will get
and then what you do it divide each one by x^1/2 and you therefore get 4x^2.5 and x^2 so
a=2.5 or 5/2 and
b=2
