Suppose 1313 is the 12unit growth factor What is the 13unit

Suppose 1.31.3 is the 1/2-unit growth factor.

What is the 1/3-unit growth factor?

Solution

Given that 1/2 unit growth factor = 1.3

then 1-unit growth factor = 1.3*2=2.6

7-unit growth factor = 2.6*7 = 18.2

1/9-unit growth factor = 2.6*(1/9) = 0.288888888889
which is approx 0.29

1/13-unit growth factor = 2.6*(1/13) = 0.2

1/3-unit growth factor = 2.6*(1/3) = 0.866666666667
which is approx 0.87
