METHOD 1
f(3) = 20
f(4) = 30
f(5) = 42
f(6) = 56

rate of change
f(4)-f(3)=10
f(5)-f(4)=12
f(6)-f(5)=14

then the average of change is 10+12+14 /3 = 12

METHOD 2 --- faster

rate of change = f(6)-f(3) / 6-3
= (36+18+2)-(9+9+2) / 3
= 36/3 = 12

The difference of seven halves and six quarters is multiplied by negative two fifths. Find this rational number.

malfutka [58]

First, the difference is 7/2 - 6/4 = 14/4 - 6/4 = 8/4

Now multiply it: 8/4 x (-2/5) = -16/20 = -4/5
