The population of a town is 30,000, and it grows at a rate of 7.2% per year.
What will the population be in 6 years?

The population in 6 years will be 42,960.

Step-by-step explanation:

First, multiply 7.2% or 0.072 and 30,000 which will give you 2,160.

Then, 2,160 by the number of years (6) which is 12,960.

Lastly add 12,960 and 30,000 to get 42,960.

Hope this helps and I hope u have an Amazing day!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
