we are given
population gets doubled after every 50 years
so, we can set up function as
![F=P(2)^{(t)/(50)}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/3uzejve1a2bkbuyy5149z1eirl06gb9y4g.png)
Here ,
P is initial population
t is time in years
F is future population
so, we have
P=2500000
t=2100-1950
t=150
we can plug these values
and we get
