Answer:

D f(n) = 7n-12

Step-by-step explanation:

The first term is -5

The second term is -5+7 =2

The common difference is 7

an = a1 +d(n-1) where d is the common difference

= -5 +7(n-1)

Distribute the 7

= -5 +7n -7

7n -12

A city has a population of 240,000 people. Suppose that each year the population grows by 7.75%. What will the population be aft

emmasim [6.3K]

Answer:

$\large\boxed{\sf \ \ \ 404,699 \ \ \ }$

Step-by-step explanation:

Hello,

At the beginning the population is 240,000

After 1 year the population will be

240,000*(1+7.75%)=240,000*1.0775

After n years the population will be

$240,000\cdot1.0775^n$

So after 7 years the population will be

$240,000\cdot1.0775^7=404699.058...$

So rounded to the nearest whole number gives 404,699

Hope this helps
