Question

How do I write a recursive funtion for 2000 trees to start with and it increases by 200 trees per year?

Answer 1

`f(0)=2000`

`f(t+1)=f(t)+200`

Explanation:

We are given

initial number of trees is 2000

so,

`f(0)=2000`

Let's assume

t is the time in years

it increases by 200 trees per year

So, after t years, we can write as

`f(t+1)=f(t)+200`

So, our recursive function is

`f(0)=2000`

`f(t+1)=f(t)+200`
