I can see an approximate pattern here.

$\displaystyle \frac{f(20)}{4}\approx{f(40)}$

$\displaystyle \frac{f(40)}{3}\approx{f(60)}$

$\displaystyle 2$

$\displaystyle 1$

$\displaystyle ?$

I'm not sure what it means, but maybe I've helped. Don't you have a graphing utility with regression capabilities?
