If a population's per capita growth rate is 0.02 and its population is 100000000 how large will the population be in 5 years

After 1 year: 100,000,000 x 1.02 = 102,000,000

after 2 years: 102,000,000 x 1.02 = 104,040,000

after 3 years: 104,040,000 x 1.02 = 106,120,800

after 4 years: 106,120,800 x 1.02 = 108,243,216

and after 5 years: 108,243,216 x 1.02 = 110,408,080
