Example Question #1 : How To Find The Missing Part Of A List
What is the value of n in the sequence below?
The numbers increase by 5. Given that the number before n is 20, the value of n is .
Example Question #1 : How To Find The Next Term In An Arithmetic Sequence
What is the next term in the following sequence?
What is the next term in the following sequence?
This is an arithmetic sequence with a common difference of . To find the next term in an arithmetic sequence, add the common difference to the previously listed term:
Example Question #2 : How To Find The Missing Part Of A List
Find the missing number in the sequence:
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 #5 : How To Find The Missing Part Of A List
What is the missing number in the following list:
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 #4 : How To Find The Missing Part Of A List
Find the missing number in this set:
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 #3 : How To Find The Missing Part Of A List
Find the next number in the list:
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 #4 : How To Find The Missing Part Of A List
Find the missing number:
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 #5 : How To Find The Missing Part Of A List
Find the missing number in the list below:
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 .
Example Question #21 : Data Analysis
What is the missing number in the following sequence:
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 . Therefore, the missing number is , because
Example Question #12 : How To Find The Missing Part Of A List
Find the missing number in the sequence:
In this sequence of numbers, there is an important pattern to recognize. Each number is greater than the number prior to it by double the difference between the two previous numbers. is greater than by a difference of , therefore the number that is missing must be greater than by a margin of . Thus, the correct answer is . Notice that is also less than by a difference of
