Answer:
The explicit form for the sequence is: 
Step-by-step explanation:
In order to find an explicit form for the given sequence, you have to use the definition of arithmetic sequence and the <em>explicit formula</em>.
An arithmetic sequence is defined as a sequence where the difference of two consecutive terms is a constant.
The <em>explicit formula </em>is:

Where a1 is the first term, d is the common difference and an is the nth term of the sequence.
You have to subtract two consecutive terms to obtain d:
24-13= 11
35-24=11
Therefore d=11
In this case a1=13
Replacing in the formula:

From 4pm to 5pm the temperature dropped 11.55 degrees
noon 85.4 + 3.85 = 89.25
1st hr 89.25 + 3.85 = 93.1
2nd hr 93.1 + 3.85 = 96.95
3rd hr 96.95 + 3.85 = 100.8
4th hr 100.8 ??
5 pm 89.25
100.8-89.25= 11.55
