The average rate of change in this case is Change in people/ Change in time. All you have to do is plug in the numbers.
Change in people is 7.63 billion people - 6.4 billion people = 1.23 billion people
Change in time is 2018 - 2004 = 14 years
Plug those into the formula and you get *drum roll please
...
...
.0879 Billion people per year or
87.9 Million people per year
FYI this is a linear change question but the population would follow an exponential change so don't use the answer in real life.

formula ---> average rate = (7.63 - 6.4)/14 = 0.0879 billion/year
