**Answer:**

An annual increase of 3.24% of the population.

**Step-by-step explanation:**

The population did not increase by the same number each year, because:

First 5 years:

1000 - 1162 = 162 people

Second 5 years:

1350 - 1162 = 188 people

Third 5 years:

1568 - 1350 = 218 people

What it says is that numerically the same number of people did not increase every 5 years, but if I increase by the same percentage, to calculate this percentage we divide the new people by the number that there were originally, that is to say:

First 5 years:

162/1000 = 0.162 = 16.2%

Second 5 years:

188/1162 = 0.1618 = 16.2%

Third 5 years:

218/1350 = 0.1615 = 16.2%

Which means that per year I increase by:

16.2 / 5 = 3.24%
