After a year the population will be 98.6% (100% - 1.4%) 98.6% as a decimal is 0.986 ... so after 1 year it will be: <span>

3800 x 0.986 

after 2 years it will be: 

3800 x 0.986 x 0.986... 

after 3 years: 3800 x (0.986)^3 

<span>in 2018. And after 4 years it will be 3800 x (0.986)^4 = which is 3591.62724 or 3592</span></span>
