Answer:
Arithmetic sequence.
Step-by-step explanation:
We have been given 9,5,1 and -3
We need to check what kind of sequence is this.

d is common difference we will check difference of consecutive terms.



We can see the difference between all the terms are same that is -4
So, this is an arithmetic sequence.
Arithmetic sequence is the sequence in which the difference between consecutive terms are same.
The total cost will be $56 because 3 x 8 = 24 so then you multiply 7 x 8 = 56.
You could use a thermometer on a pets fur if it was outside or measure the amount of air in a ball since air is heated it expands there for making the ball have more air? it’s a long shot but i would just go for the first idea to be honest
My favorite way is to hold down Ctrl, Alt, and Delete all at once. This will open up a screen on you computer where you can select Task Manager.
Suppose that the exponential growth function is y = 4^x.
If x = 1, then y = 4^1 = 4.
If x = 3, then y = 4^3 = 64.
Let the initial value be 1/2.
The growth function is now y = 1/2 * 4^x.
If x =1, then y = 2 which is half of the y value before adding the 1/2.
If x = 3, then y = 1/2 * 64 = 32.
Answer: 1/2
