Alicia works at a pretzel factory. In the graph at right, the x-axis represents time in minutes and the y-axis represents the number on pretzels twisted Line A represents the rate at which Alicia twist pretzels. a. Using the graph, draw line B, representing the rate of someone who twists pretzels.

b. Explain how you determined where to draw line B

, and

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

, and for

the answer is mp
