The nth term of a sequence exists 2n2² - 4n+4 is 36.
<h3>What is PEMDAS' order of operations?</h3>The order of operations exists as a rule that describes the right sequence of measures for estimating a math expression. We can recognize the order utilizing PEMDAS: Parentheses, Exponents, Multiplication, and Division (from left to right), Addition, and Subtraction (from left to right).
Follow the PEMDAS order of operations
Calculating the exponents, we get 2² = 4
= 64-32 +4
= 36
Therefore, the nth term of a sequence that exists 2n2² - 4n+4 is 36.

This question is incomplete as no image was attached. Please find the missing image in the attachment. Also, this is the correct question:
Cal's go cart has a gas tank with the dimensions shown below. He uses a gas can that holds 1 gallon of gas, to fill the go cart tank. 1 gallon = 231 inches^3. How many full gas cans will it take to fill the go cart's gas tank?
Answer: 2 full gas cans
Step-by-step explanation:
From the image, we have the following dimensions:
length, l = 15.4 inches (in)
width, w = 10 in
height, h = 3 in.
The volume of the gas tank (which is rectangular) is given as:
NB: The unit of volume is cubic units. In this example, it is cubic inches.
The gas can being used to fill the tank holds 1 gallon of gas =
The total volume to be filled is of gas.
So, it will take full gas cans to fill the go cart's gas tank.
Therefore, the answer is 2.
