Increasing =2522000

years ago population =16000000

Step-by-step explanation:

Let years ago population

If initial amount =P, rate of increase and time

after years amount $(A)=P(1+\frac{r}{100})^t$

Hence A=18522000

$P=x\\r=5\%\\t=3\ years$

$18522000=x(1=\frac{5}{100})^3\\\\18522000=x(1.05)^3\\\x=\frac{18522000}{(1.05)^3}\\\\x=\frac{18522000}{1.1576625}\\\\x=16000000$

$3\ years\ ago\ population\ =16000000\\\\Increase=1852000-16000000\\\\=2522000$
