Each day, amaya studies language flashcards and then reads some pages in a novel, as shown in the table. take a scatter plot of the total time she studies as a function of the number of pages she reads. draw a trend line. pages: 4 6 8 10 12 time (min): 27 32 39 45 51 What type of correlation does the scatter plot in Part A show?
Which could be an equation of a trend line for the data in Part A

72 is the answer to this problem

1/800 is the right answer

, and

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
