NO links please!!! Suppose the average temperature for a 4‐day period in Chicago, Illinois, is ‐8°. After the next day, the 5‐day average is ‐9°. What was the low temperature for the fifth day? Explain your reasoning by showing your work or writing down your thoughts and answer.

(Hint: One way to solve this is to make an equation from what you know about the temperatures.)

Giving brainliest to the person with the CORRECT answer and the best CORRECT explanation of how you got the answer!

depends on how many days you are talking about

step-by-step explanation:

, 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
