Levi has joined the a Frequent Coffee Buyer program with a local cafe. The program costs $5 per month which allows him to get a discounted coffee price of $3 per cup. Answer the questions below regarding the relationship between the of number of cups of coffee purchased and the total monthly cost. The independent variable, x, represents the
total monthly cost
, and the dependent variable is the
number of coffee cups purchased
, because the
total monthly cost
depends on the
number of coffee cups purchased
.
A function relating these variables is A(x) =A(x)=
.
So A(12) =A(12)=
, meaning 1212
cups of coffee will cost

dollars monthly
.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
