Understanding the Missing Numbers and Series

The missing numbers are the numbers skipped in several identical variations between published series.

The missing numbers are the numbers skipped in several identical variations between published series. The spelling of a missing number is defined as finding the relevant difference between a particular number and entering the missing word on each line and position. These are the numbers that are missing from a particular set of numbers that have similar differences. Writing missing numbers is known as finding similar changes between those numbers and putting the missing values on a particular line and number.

 

In this article, we will touch upon the basic components and use various examples to find a missing number in a sequence.

 

Missing number series

The Missing Number series begins with a few examples. The missing number can be at the beginning or end of the series. As you can see, this creates different levels of difficulty. The strategy for the missing series of numbers is the same as for the wrong series of numbers. You need to be aware of the rule and use it to predict the next number. Here are some tips to help you reduce the time you spend on a particular company trying to understand the rules that make up a set of numbers.

 

• Select the term 2/3 to test the rule. So, for example, if you have five terms, select at least three of them to test your prediction rules. 
• When choosing a term to test, choose the term that is most accessible. These include terms with coefficients of 2, 3, 5, or 10—test common rules such as term sums, squares, cubes, and other formulas.

 

How to solve missing number series?

To do this, you first need to understand the question well. Try to find a pattern in the series. Then apply this pattern to the adjacent numbers on the line. Here's how you get to the solution:

 

• Please read the question carefully. You may be able to solve the problem just by reading the question. Example: Search for mission numbers in the series: 2, 4, 6,? , 10.
• After reading this question, you will find that all the numbers are even. Therefore, you can find the answer. The correct answer is 8.
• Observe whether the series is increasing or decreasing. This observation saves our time. This method gives us a rough idea of what the pattern in the series looks like.
• Check if the number suddenly goes up or down. It helps you understand the rate of change of numbers. You can add or subtract when the numbers are slowly rising or falling. But if the number changes suddenly, you have to move to multiplication, division, square, or cube.
• If you try hard and still don't find the answer, you can ensure that the series follows a different pattern. Example: Find the missing numbers in the series: 4, 8, 9, 18, 21,? ,
• Here you can see that the first number in the row is exactly twice the second number.
•  Therefore, you can find the answer that is 42. If there are extreme changes in the series, test the cubic series.

 

Different types of number series

 

Here are some most common patterns followed by a series of numbers:

 

• Perfect Cube Series: One of the series numbers is missing, based on the number of dice in a particular order.
• Geometric series: Based on the ascending or descending order of the numbers, each subsequent number is obtained by dividing or multiplying the previous number by a specific number.
• Arithmetic progression: Consists of a series that finds the next term by adding or subtracting a constant from the previous term.
• Two-stage series:  In a two-stage arithmetic progression, the difference between consecutive numbers forms an arithmetic progression by itself.
• Mixed Series: This particular type of series may have multiple patterns in a single series or may have been created according to unorthodox rules.
• Series consisting of perfect squares: In most cases, a series based on a perfect square is based on the perfect square of a number in a particular order, and usually, one of the numbers in this type of series is missing.
• Twin/ Alternate series: As the name of the series suggests, this type of series can consist of two series combined into one series. The alternating terminology of this series can form an independent series.
• Arithmetic-Geometric Series:  As the name implies, the Arithmetic Geometric Series is formed by a special combination of arithmetic progressions and geometric progressions. An important feature of geometric progressions is that the differences between consecutive terms are in geometric progressions. The Geometrico Arithmetic Series is the opposite of the Arithmetic Geometric Series. The difference in thought-provoking concepts lies in the arithmetic progression.

 

Conclusion 

Sequence questions are common in most management skills tests. These questions are based on numbers that follow logical rules/patterns based on the concept of elementary arithmetic. Specifies the specific series for which the pattern needs to be analyzed. Hope this article helped you understand the missing series. Remember that reasoning is entirely based on your ability to understand the question. Only practice can enhance this ability.

 

Frequently Asked Questions

Q) What can you do first to find the missing number in any given sequence?

 

Answer: Following things can be done to find missing numbers in a series:

 

• Observe the numbers in the row, whether in ascending or descending order. 
•  Next, calculate the difference between the numbers. 
•  If the difference is large, check multiplication or division.
•  Still, note that the difference is large before checking the square or cube.

 

What does "wrong series of numbers" mean?

Answer: A series of numbers that follow a logical pattern. However, there is one number that does not follow the pattern. You have to find that number. It is known as the wrong set of numbers.

 

What is the easiest way to find the missing number?

Answer: Most questions are based on the simple difference between the two numbers. Therefore, you need to understand the difference first.

 

How can I save time in solving series?

Answer: Please read and understand all kinds of series first. Speed up your analysis and save time.
