Question

A certain species of tree grows an average of 3.1 cm per week. Write an equation for the sequence that represents the weekly height of this tree in centimeters if the measurements begin when the tree is 400 centimeters tall.

Answer 1

h = 400 + 3.1(n - 1)

Explanation:

this is an arithmetic sequence so instead the answer would be

h = 400 + 3.1(n - 1)

where h is the height of the tree after n weeks

Answer 2

y=3.1x+400 The x is how much it grows per week and the 400 is where it started at. the y is how tall it is after x weeks
