56/8 = 7
7*5 = 35
7*3 = 21
Hope this helps !

ANSWER
Average Rate of Change

EXPLANATION
To find the average rate of change of y=f(x) from x=a to x=b means finding the slope of the secant line joining the points
(a,f(a)) and (b,f(b))
The slope of the secant line joining these points is

This gives the average rate of change of the function.
X • 1.5 = 300
So...
300/ 1.5 = 200
