Question

A city's population is currently 500,000. If the population doubles every 65 years, what will the population be 130 years from now?

Answer 1

2,000,000

Explanation:

Simple maths, really.

65 times 2 is 130, and the population is already 500,000 with no time passing. 65 years later, the population would be 1,000,000. 65 years after that, the population would double again, so the answer would be 2 million.

Hope this helped!
