Example Questions

Example Question #1 : How To Find The Missing Part Of A List

Find the missing parts of this set:

27, 36, 45, 54, ___, ___, 81

Possible Answers:

Correct answer:

Explanation:

First, you must notice that the set is counting up/forwards. When you look at how all the numbers are related, you will notice that these numbers increase by 9, or are multiples of 9. To solve you can add 9 to the last known number and then 9 to the next:

 

Or you can count by 9 to fill in the missing numbers.  The complete set is: 27, 36, 45, 54, 63, 72, 81.

Example Question #6 : How To Find The Missing Part Of A List

What are the next two numbers in the sequence below?

Possible Answers:

Correct answer:

Explanation:

In the number sequence , the first number is multiplied by  to get the second number. The second number is divided by  to get the third number. Numbers are then alternately multiplied by  and divided by  as the sequence continues.

Since  is divided by  to get  at the end of the given numbers, the next step is to multiply by . This gives the number  as the next in the sequence. The pattern is to divide by  after multiplying by , so the number after  is given by  divided by , which is .

Example Question #2 : How To Find The Missing Part Of A List

Find the missing numbers in the set.

Possible Answers:

Correct answer:

Explanation:

The pattern in the set is to add three every time.  The last number of the set given is 19 so add 3 and get 22.  Add 3 again and get 25. Add 3 again and get 28. Thus the answer is 

Example Question #3 : How To Find The Missing Part Of A List

What is the missing number in the sequence?

Possible Answers:

Correct answer:

Explanation:

To find the next number in the sequence, we need to find the pattern. In this problem, the pattern is adding by seven! So, to find the first number, we need to subtract seven from the number after the blank.

Example Question #4 : How To Find The Missing Part Of A List

What is the missing number in the sequence?

Possible Answers:

Correct answer:

Explanation:

To find the next number in the sequence, we need to find the pattern. In this problem, the pattern is subtracting by ten! So, to find the first number, we need to subtract ten from the number before the blank.

Example Question #5 : How To Find The Missing Part Of A List

What is the missing number in the sequence?

Possible Answers:

Correct answer:

Explanation:

To find the next number in the sequence, we need to find the pattern. In this problem, the pattern is adding by threes.

Example Question #11 : How To Find The Missing Part Of A List

What is the missing number in the sequence?

10, __, 4, 1

Possible Answers:

Correct answer:

Explanation:

To find the missing number in the sequence, we need to find the pattern. In this problem, the pattern is subtracting by three! So, to find the missing number, we need to subtract three from the number before the blank space.

Example Question #42 : Data Analysis And Probability

What is the missing number in the sequence?

2, 6, __, 54

Possible Answers:

Correct answer:

Explanation:

To find the missing number in the sequence, we need to find the pattern. In this problem, the pattern is multiplying by three! So, to find the missing number, we need to multiply the number before the blank space by 3.

Example Question #43 : Data Analysis And Probability

What is the missing number in the sequence?

1, 5, __, 125

Possible Answers:

Correct answer:

Explanation:

To find the next number in the sequence, we need to find the pattern. In this problem, the pattern is multiplying by five! So, to find the missing number, we need to multiply the number before the blank space by 5.

Example Question #44 : Data Analysis And Probability

What is the missing number in the sequence?

27, 18, __, 0

Possible Answers:

Correct answer:

Explanation:

To find the next number in the sequence, we need to find the pattern. In this problem, the pattern is subtracting by nine! So, to find the missing number, we need to subtract 9 from the number before the blank space.
