Hello, delgeezee!

Assume the pop. of world in 2002 is 6.2B and growing at a rate of 1.3% each year.

a. Set up a recurrence relation for pop. n years after 2002.

b. find an explicit formula for the pop. of the world after n years.

c. What will be the pop. on 2022?

The recurrence relation I came up with is

A(n+1)= 1.3*A(n), where A(n) is 6.2B

You don't understand percents, do you?

The population increases each year by a factor of 1.3% or 0.013.
