Solve the problem.The following table shows a country's population from 2014 to 2017:
Divide the population for each year by the population in the preceding year. Use this ratio to write the general term of the geometric sequence describing the country's population growth n years after 2013. Then estimate the country's population , in millions, in 2022.
A. an = 10.10(1.02)n-1 ; 14.21 million B. an = 10.10(1.03)n-1 ; 13.18 million C. an = 10.10(1.02)n-1 ; 14.92 million D. an = 10.10(1.03)n-1 ; 12.79 million
