Generally, average rate of change of f(x) in interval [a, b] is \[\large \dfrac{f(b)-f(a)}{b-a}\]

So here you just have \(\dfrac{f(5)-f(1)}{5-1}=~\cdots~?\)

you just plug in the 5 value into the equation you have subtract it by the equation with 1 plugged in and then put it over 5-1 which is 4.

you're solving wrong. what did you get for 5^3-5 ?

it should be ->( (5^3-5)-(1^3-1))/4
