Solve the problem.The following table shows a country's population from 1995 to 1998:
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 1994. Then estimate the country's population, in millions, in 2005.
A. an = 12.10(1.04)n - 1; 18.63 million B. an = 12.10(1.04)n - 1; 17.91 million C. an = 12.10(1.03)n - 1; 20.44 million D. an = 12.10(1.03)n - 1; 21.67 million
