The average cost per bicycle in dollars to build x bicycles is modeled by the function below A(x)=80x+2400/x. How many bicycles must be built for the cost to be $200 per unit? Show your work

step-by-step explanation:

first one is a: renaming a fraction. second one is c: de-c

for

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
