Use n = 52 in the formula.
F = n/4 + 37
Replace n with 52:
F = 52/4 + 37
F = 13 + 37
F = 50
Answer: The estimated temperature is 50 deg F.

<h3>What is Arithmetic progression series?</h3>
Arithmetic Progression (AP) is a sequence of numbers in order in which the difference of any two consecutive numbers is a constant value.
Given that: t(n) = −9 + 21n=l
a= 12, Sum = 3429
As, Sum of series =3429
n/2 (a+l) =3429
n/2 (12 +21n-9)= 3429
n/2 (3+21n)=3429
21n² + 3n= 6858
21n² + 3n- 6858=0
7n² + n- 2286=0
For solving for n, get
n= 18 or n= -127/7
Thus, there 18 terms in the series.

Answer:
$960
Step-by-step explanation:
A shortcut method.
If you get a discount of 1/5, then that means you would end up paying 4/5 of the whole cost. That means all you have to do then is plug in what it costs, which in this case is 1200, and then multiply it by 4/5, so you end up with $960.
