the population in 1992 was 83 mill....population is 1996 was 88 mill...
so in 4 years (from 1992 to 1996), the population rose by (88 mill - 83 mill) = 5 mill
Thats 5,000,000 / 4 = 1,250,000 per year.
so in 2013 (17 years from 1996), the population would be :
83 mill + 1,250,000(17) = 83 mill + 2,125,000 = 85,125,000 <==
