Question

One year after you buy a tree, it is 15 feet tall. Each year after you buy the tree, it grows 2.5 feet. Write a function that represents the arithmetic sequence. How long does it take for the tree to reach its maximum height of 25 feet?

ALSO
What is the function?

Answer 1

hey! this is your answer:

Explanation:

function =

f(n)= 2.5n + 15

It takes 4 years for it to grow to 25 ft.

becuase,

25= 2.5(4) + 15

the equation equals itself out when 4 is put in.
