______ people?

Answer 1

8,000,000 or 2,000,000

Explanation:

For 8,000,000=

1st 50 years= 500,000+500,000= 1,000,000

2nd 50 years= 1,000,000+1,000,000= 2,000,000

3rd 50 years= 2,000,000+2,000,000= 4,000,000

4th 50 years= 4,000,000+4,000,000= 8,000,000

For 2,000,000=

200 years ÷ 50 years= 4

500,000×4= 2,000,000
