Understanding Alphanumeric series

Candidates are required to answer questions based on alphanumeric series, which are a combination of number-based, alphabet-based, and symbol-based series. The candidates’ answers must be based on the series. In the reasoning ability section, the alphanumeric series generally covers two to three questions. This topic is one of the ones that is asked about the most frequently in the various government exams.

In addition to being simple to respond to, the questions based on alphanumeric sequences are scored, and they are one of the most prevalent types of logical reasoning topics. 

Alphanumeric series: 

An alphanumeric series is a series that is formed by combining both alphabets and numbers, as the name suggests. This type of series is also known as an alphabetic series. The majority of questions pertaining to this subject can be found in the introductory section of any and all government examinations. 

Candidates can anticipate being asked at least one to three questions relating to this topic while taking the exam. The questions pertaining to this topic are straightforward and easy to solve. 

Formats in alphanumeric series: 

When it comes to the alphabetical number series, there is a wide range of possible question formats to choose from. These are the following: 

Missing series: 

In other cases, a sequence of letters and numbers might be arranged in a specific pattern, and the applicants might be requested to complete the task by filling in the blanks with the appropriate component. 

Alphabet – Number symbol: 

These questions may also be posed in a format in which a series containing alphabets, numbers, and various types of symbols (such as &, *, $, etc.) may be presented, and questions may be asked based on them.  

Only alphabetic series: 

There may be a series of questions with either missing elements or questions having sub-parts to be asked. These questions will only contain the alphabets of the English language and will not contain any numerals. 

Only numerical series: 

The test may include questions about series that simply contain numbers and are arranged in a particular pattern. It’s possible for questions of this type to be posed as a rearrangement of numbers or digits, with the numbers being presented in an ascending, descending, or any other sequence. 

Tips and tricks to solve Alphanumeric questions: 

The following are some hints and suggestions that you can use to improve your chances of successfully completing the questions based on the alphabetic series: 

• When solving a pattern-based series, you should begin by analysing the alphanumeric series that you have been given and attempting to decipher the pattern that is being followed. In most cases, the pattern will involve a shift in the terms that come immediately after or before it, whether they be numerical or alphabetical.
• In abrupt series, such as number-symbol-alphabet, the general rule is that there is no pattern that is followed. Candidates are required to proceed to the subsequent section of the questions and immediately answer those questions.
• Make sure that after finding an answer to a missing number series, you check the entire series again to see if you have made any mistakes. This is to ensure that no mistakes have been made.

Solved examples: 

The following are a few examples that have been solved in order to help candidates comprehend the concept of alphanumeric series and to offer candidates with examples that can be used to prepare for the examination: 

Directions (Q1-Q2): Please answer the following questions by referring to the alphabetic series that has been provided below: 

A * 5 9 I N & E @ # U 1 & 

Q1. How many of the vowels in the preceding sequence have a symbol located before them? 

1. One
2. Two
3. Three
4. None

Answer: (2) Two; “E” is preceded by “&” and “U” is preceded by “#” 

Q2. What is the name of the element that is the second element to the left of the element that is the sixth element from the right? 

1. &
2. @
3. N
4. E
5. 9 

Answer: (3) N; Sixth element from the right is E and second to its left is N 

Directions (Q3-Q4): Please answer the following questions with reference to the numerical series that is provided below: 

435 224 786 823 902 

Q3. Which of the numbers becomes the highest when all of the digits in each of the given numbers are rearranged so that they are in ascending order? 

1. 435
2. 224
3. 786
4. 823
5. 902 

Answer: (3)786 

Solution: The following new numbers are produced when the digits of the number are positioned within the number in ascending order: 

435 – 345

224 – 224

786 – 678

823 – 238

902 – 092 

Q4. Which number yields the lowest product when the digits contained within it are multiplied with each other to create a new number? 

1. 435
2. 224
3. 786
4. 823
5. 902 

Answer: (5)902; When any number is multiplied by zero, the resulting response is always zero, which is the smallest possible value. 

Conclusion: 

In the section on reasoning, there is a significant amount of weightage assigned to the alphabetic series. Candidates who have a comprehensive understanding of the material will have an easier time solving the alphabetic series questions. The familiarity of strategies and methods to handle this problem ensures that there is a low potential for errors. The applicants should get plenty of practice solving questions in order to increase the speed with which they can solve questions using alphabetic sequences.
