A certain species of tree grows an average of 0.5 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 200 centimeters tall.

Question

anonymous · Answer

well the trees initial height is 200

is grows .5 cm every week

Thus, 200 + .5 would give the next week

A more general way of writing that is 

y = 200 + .5x

where x is the number of weeks. Like, if you want to know how big the tree will be after 5 weeks, you can say 200 + .5(5)
