The answer is 8,686,308,783.
To calculate this, we will use the equation for exponential function:
[tex]y=x(r+1) ^{n} [/tex]
y - the future population
x - the current population
r - the rate of increasing the population
n - the number of years
It is given:
x = 6,486,915,022
r = 1.4% = 0.014
n = 2026 - 2005 = 21
Therefore:
[tex]y= x(r+1)^{n} =6,486,915,022*(0.014+1) ^{21} = 8,686,308,783 [/tex]
