In this sequence, every subsequent number is 7 less than the preceding number. Given that the number that precedes w is 71, the value of w is . Therefore, 64 is the correct answer.

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

What is the value of n in the sequence below?

**Possible Answers:**

**Correct answer:**

The numbers increase by 5. Given that the number before n is 20, the value of n is .

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

Find the missing number in the sequence:

**Possible Answers:**

**Correct answer:**

In this sequence, the difference between each number is double the difference between the number that came prior to it in the sequence. For example, and . Thus, the missing number must be greater than by a difference of and therefore

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

What is the missing number in the following list:

**Possible Answers:**

**Correct answer:**

In this sequence of numbers, there is an important pattern to recognize. In this sequence each number is a prime number, however the sequence skips every other prime number. Thus, the sequence begins with the prime number and then skips the prime number (which is the only even prime number) and goes to . From the next prime number is , however since the pattern in this sequence skips every other prime number--the missing number is .

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

Find the missing number in this set:

**Possible Answers:**

**Correct answer:**

In this sequence of numbers, there is an important pattern to recognize. Each number in this sequence is a composite number--however, the sequence skips every other composite number. Thus, the next composite number after is --which is skipped because of the pattern, making the correct answer .

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

Find the next number in the list:

**Possible Answers:**

**Correct answer:**

In this sequence of numbers, there is an important pattern to recognize. Each number is greater than the number prior to it by a margin of . In other words, each number in this list is a multiple of . Thus,

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

Find the missing number:

**Possible Answers:**

**Correct answer:**

In this sequence of numbers, there is an important pattern to recognize. Each number is greater than the number prior to it by a margin of . Thus, the correct answer is , because

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

Find the missing number in the list below:

**Possible Answers:**

**Correct answer:**

In this sequence of numbers, there is an important pattern to recognize. Each number is greater than the number prior to it by a margin of 9. Thus, the correct answer is because .
