Consider a population that grows according to the recursive rule `P_n = P_(n-1) + 90`, with initial population `P_0 = 50`.

Then:

`P_1` =

`P_2` =

Find an explicit formula for the population. Your formula should involve `n` (use lowercase n)

`P_n = `

Use your explicit formula to find `P_100`

`P_100` =

Then:

`P_1` =

`P_2` =
