Here the growth is exponential. The number of offsprings are increasing in the multiples of 2.
So the formula used here would be-
Number of offsprings = [tex] 2^{n} [/tex]
where n = number of generations
Number of children in third generation = [tex] 2^{3} [/tex] = 8
Number of children in fifth generation = [tex] 2^{5} [/tex] = 32
This is the most commonly used equation where population doubles itself after every generation.
