You could use the compound interest formula. For this question the number of people compounds annually, so the formula is simplified.

P = C(1+r)^y
Where P is the future population
C is the current population
r is the growth rate expressed as a decimal (0.014 in this case)
and y is the number of years (19)

P = 6,486,915,022(1.014)^19 in other words.

Hope that helps.

Note that you must complete the exponent first (1.014^19) according to the order of operations ... just in case you missed that. Your answer should be a little over 9 billion if you want to know if you're on the right track.
