Suppose there are L₀ people in the world today. If the population growth rate equals $\bar { n }$ ,
then in 50 years, the world population will be $L _ { 50 } = L _ { 0 } \Sigma _ { t - 0 } ^ { 50 } ( 1 + \bar { n } ) ^ { t }$ .

Question

Suppose there are L₀ people in the world today. If the population growth rate equals

\bar { n }

,
then in 50 years, the world population will be

L _ { 50 } = L _ { 0 } \Sigma _ { t - 0 } ^ { 50 } ( 1 + \bar { n } ) ^ { t }

.

Quizplus · Accepted Answer

The formula given is incorrect for calculating population growth. The correct formula for exponential growth is $L_{50} = L_{0} \times (1 + \bar{n})^{50}$. The summation notation used in the original statement is not appropriate for this context.
