1) Li Na is saving money. Her parents gave her an amount to start, and since then she has been putting aside a fixed amount each week. After six weeks, Li Na has a total of
$82. Fourteen weeks from the start of the process Li Na has $118.
a) using x for the number of weeks and y for the amount in savings (in dollars), construct
a linear function that describes the relationship between the number of weeks and the
amount in savings.

Answer : Y^2 - Y^1 over X^2 - X^1 covert the points given
4.5 is the slope
Y=Mx+b
Y=4.5x+55
B=55

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
