The reasoning section is a common section that is always a part of all competitive exams which are generally conducted throughout the year. The reasoning section is designed to access a candidate’s ability to think logically and analyze given data to solve problems fastly. The Alphanumeric series is an important topic in the reasoning section. Further down the line, we will see how to solve alphanumeric series with the help of some sample questions.
What is an Alphanumeric Series?
As the name suggests, Alpha and numeric, is a series that is formed by mixing both alphabets and numbers. Symbols are also sometimes included in alphanumeric series. Hence we can say that an Alphanumeric series is a combination of alphabet, number, and symbol.
An example of an alphanumeric series is – *A 5 9 I N & E @ # U 1 &**
Questions from the alphanumeric series are mostly asked in the preliminary phase of all Government exams. Alphanumeric series questions are simple to answer, and candidates could expect at least 13 questions from them on the exam.
Tips and Tricks to Solve Alphanumeric Seriesbased Questions
There is a range of types from which questions may be asked for alphanumeric series. These types are
 Missing Series: A series of alphabets and numbers may be given a certain pattern, and applicants may be asked to fill in the blank area with the required element.
 AlphabetNumberSymbol: These questions may also be asked in a format in which a series of alphabets, numbers, and various types of symbols (such as &, *, $, etc.) are given, and questions are asked based on them.
 Only Alphabetic Series: A series arranged in a particular way with either a missing element or questions with subparts made up of only alphabets and no numbers are asked.
 Only Numerical Series: In an exam, candidates may be asked only about numerical series that are arranged in a particular pattern. This type of question may be asked in the form of a rearrangement of numbers or digits, with the number in ascending, descending, or any other order.
Let’s discuss a few tips and tricks that may help in solving questions on alphanumeric series:

In patternbased series, first, analyze the given alphanumeric series and try to figure out the hidden pattern that is being followed. Generally, the pattern may involve a change in succeeding or preceding terms of the number or alphabet.

In abrupt series, a series which consists of numbersymbolalphabet, no pattern is usually observed. Candidates must proceed to the subset of questions and answer them immediately.

To confirm that no errors have been made, recheck the full series after obtaining an answer for the missing number series.
Alphanumeric Series: Solved Sample Questions
Listed below are a few sample questions from the Alphanumeric series to help you strengthen your concept.
Directions (1β4): Based on the arrangement below, answer the following questions
N # P 3 H R $ 5 % G 6 K M & I D @ L F 2
Q1. If the symbols followed by consonants interchange their positions within the group, then which element is fourth from the right end?
(a) @
(b) &
(c) L
(d) D
(e) None of these
Correct Option β c
Now let’s do some analysis
Analysis:
Given series β N # P 3 H R $ 5 % G 6 K M & I D @ L F 2
After operation β N P # 3 H R $ 5 G % 6 K M I & D L @ F 2
So, the fourth element from the right end = L
Q2. How many vowels in the above arrangement are preceded by a symbol?
(a) One
(b) Two
(c) Three
(d) None
(e) Four
Correct Option β a; βIβ is preceded by β&β.
Q3. Which is the Third element to the left of the Fifth element from the right?
(a) &
(b) K
(c) D
(d) M
(e) 6
Correct Option β d; the Fifth element from the right is D and the third to its left is M
Q4. If all the symbols in the arrangement are removed, which element will be 7th from the left end?
(a) 5
(b) K
(c) 6
(d) M
(e) G
Correct Option: e
Explanation: If we remove all the symbols (#,$,%,&,@), the remaining elements are N, P, 3, H, R, 5, G, 6, K, M, I, D, L, F, 2. Counting 7 elements from the left end, we get to the letter G.
Directions (5β6): Missing element in the series
Q5. Find the missing term in the given below series
ABD EFI JKO ?
(a) RSX
(b) TUZ
(c) PQV
(d) QRW
Correct Option: c
Explanation:
Q6. Find the missing term in the given below series
CEG ? OQS UWY
(a) JLN
(b) HJL
(c) KMO
(d) IKM
Correct Option: d
Explanation:
Directions (7β8): Answer the following questions using the numerical series given below
534 442 768 283 209
Q7. When all the digits in each of the given numbers are arranged in ascending order, which number becomes the highest?
(a) 534
(b) 442
(c) 768
(d) 283
(e) 209
Correct Option: c
Explanation: When the digits are arranged in ascending order within the number, the new numbers formed are:
534 β 345
442 β 244
768 β 678
283 β 238
209 β 029
Q8. When the digits within the number are multiplied with each other, the product of which number is the lowest?
(a) 534
(b) 442
(c) 768
(d) 283
(e) 209
Correct Option: e
Explanation: Any number multiplied by 0 will give the answer 0, which is the least.
Conclusion
The AlphaNumeric Series is a combination of alphabets and numbers. It may also include lower and uppercase alphabets, punctuation, and symbols. The alphanumeric series is a popular topic in competitive and government exams. Questions on this topic are frequently asked in the preliminary stages of all Competitive exams.
