Doubling population formula
WebExample 2: How to Find Doubling Time. A researcher finds that a beetle population grows from 550 to 15000 in 22 months. What is the doubling time of the beetle population? … WebFor instance, if we have a population of 50 people that grows at a rate of 10% every year, we have the following: y(t) = 50(1.1) t. At a growth rate of r%, the growth factor will be g = (1+r/100). If you would like to identify the doubling or tripling time of the population, you would only need to determine the value of g or r.
