Answer: The correct option is 1, i.e., 
.
Explanation:
The geometric sequence is in the form of,
Where, a is the first term of the sequence and r is the common ratio of the sequence.
It means the 
term of the sequence is defined as,
So the the 
term of the sequence is defined as,
It means the geometric sequence is in the form of,
Where, r be any constant.
From the options only is in the form of with common ratio 
.
Therefore, the function can be used to model the graphed geometric sequence is .
Step One
Figure out the actual change.
Change = 2.78 - 2.45
Change = 0.33
Step 2
Find the % change
% Change = 0.33/2.45 * 100 = 13.5%
I think it is a because it says the temperature is less than -5 degrees Fahrenheit
so you know the sign will have to be t<-5 degrees Fahrenheit now you are left with is t a positive or negative number a positive number would automatically be greater than -5 degrees Fahrenheit so there is no way it can be a positive number thus leaving you with one option.
Answer: a
