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 6.3B
But how do I incorporate modular exponentiation?
