Given that each subsequent number is 3 times the previous number, the value of x is 1, because 1 times 3 is 3. Therefore, 1 is the correct answer. 

The pattern in the set is that each number increases by 4. Therefore, since 4 plus 20 equals 24, x is 24. 

The set is made up of only even numbers that are below .  The only missing even number that is less than  from this set would be .

Since a die has six sides, all of the possible outcomes are  through .  

Since  is the only value in that range missing from the set, .

A factor is a number that is multiplied by another to get another value.  

To get  you may multiply 

and also 

.  

With that in mind, that answer must be .

When finding the missing part of a set, we must first look at the relationship each number has within the set.  So, looking at the set

we will look at the numbers in the set.  We can see the first three numbers are 2, 4, and 6.  How are these numbers related?  We can see that from one number to the next, we are adding 2 (if we add 2 to 2, we get 4; if we add 2 to 4 we get 6).  Let's look at the last two numbers, 10 and 12.  Does that same relationship work?  Yes, we are again adding 2 to 10 and we get 12.

So, to find the missing number in the , we will simply add 2 to the number before it.  So,

Therefore, the missing number in the set is .

In order to find the range, we must find the difference between the largest number in the data and the smallest number in the data. The easier way to locate the smallest and largest numbers in the data is to put them in order of smallest to largest.

By doing this we can see that 72 is our largest number and 4 is our smallest number. Now we find the difference between these two numbers using subtraction.

In order to find the mode of a set of data, we must find the number that occurs the most often. In this set,  appears three times, making it the most common number in the data set, so it is the mode.

The median of a set of data is the number that is physically in the middle of that data set when it is displayed in order from smallest to largest. In order to find the median of this data, we must first put it in order of smallest to largest.

Next we determine how many students there are by adding together how many students reported having each number of siblings.

Since seventeen is an odd number, one number will represent the median, and that number will be the 9^th number in the sequence. We know this because the 9^th number has eight on either side of it, putting it exactly in the middle of the data.

In our sequence, the 9^th number is , making the median of our data .

The mode is defined as the MOST in appearance. In the pack of rubber bands the color blue would appear the most in the pack.

Therefore, the mode [MOST] is Blue.
