In the next 5 years, you estimate Cardinal population sizes in the same way, and find that their size in the 2nd year is 162, in the 3^rd year is 175, in the 4^th year 189, in the 5^th year 204, and in the 6^th year is 220. What is the geometric rate of increase for this population assuming resources have been unlimited?   

Solution

Geometric rate is one per year because-

Population size difference-

2^nd year = 162, 3^rd year= 175        175-162 = 13

3^rd year=175, 4^th = 189                  189-175 = 14

4^th year=189,   5^th year= 204           204-189 = 15      

5^th year= 204, 6^thyear= 220         220-204 = 16
