Hello, Lane!

1. The polulation of a city in 1991 was 350,986.

The population of the same city in 1996 was 523,026.

Assuming that the change in the number of people is constant over five-yer periods,

find a formula for the population of the city five-year periods after 1991

and predict the population of the city in 2016.

I hope you aren't asking, "What the formula?"

. . You can baby-talk your way through it.

In the five years from 1991 to 1996, the population grew:

Assuming that this rate of change of the population is__constant__,

. . the population will increase by 172,039 people*every five years.*

Therefore, in five-year periods after 1991, the population will be:

. .

In 2016 (25 years later, or**5**five-year periods later), the population will be:

. .

2. Use the binomial theorem to expand and simplify:

What part of "binomial theorem" don't you understand?
