RRB Clerk exam is going to be conducted on the 6th of December 2025 onwards. In such a situation, this is high time you should practice topic-wise questions to get a better hold of the individual concepts. Start with topics that require less time and contain high weightage based on the past year’s experiences. One such topic is an alphanumeric series. Also, if you’ve already attempted exams like IBPS Clerk and SBI Clerk, then you’ve already mastered the basics. You just need to focus on practising and revising the concepts. In this blog, we are going to discuss the step-by-step approach to solving the alphanumeric series.

What is an Alphanumeric Series?
An Alphanumeric Series is a sequence that includes a combination of letters from A to Z and numbers from 0 to 9, and special symbols such as @, #, $, %, &, etc.
These characters are arranged in a pattern, and you’re asked to identify relationships, positions, or missing terms based on logical rules.
Example of a typical series: A 5 @ B 9 C # 3 D %
Types of Questions asked from the alphanumeric series in RRB Clerk Exam
Direct Observation Type
The given series is: A 3 B # 5 C @ D 7 E
The characters between ‘B’ and ‘E’ are: #, 5, C, @, D, 7.
The symbols in this sequence are:
- #
- @
Therefore, there are 2 symbols between ‘B’ and ‘E’.
Left or Right Position Type
Series: 8 C @ 3 D # 9 E & F
Question: Which element is 4th to the right of C?
Solution: To the right of C → @ (1), 3 (2), D (3), # (4)
Answer: #
Conditional Type
Series: A # 5 B 7 C @ 9 D
Question: If all numbers are removed, which element will be second from the right?
Solution: New series after removing numbers → A # B C @ D
Second from right = @
Answer: @
Mixed Series Type
Series 1: A 5 # 7 B
Series 2: C 9 @ D 8
Question: If the first element of Series 1 and the last of Series 2 are interchanged, what will be the 3rd element from the left in the new Series 1?
Solution: After interchange → Series 1 becomes 8 5 # 7 B → 3rd element = #
Answer: #
Count-Based Type
Series: @ A 3 B # C 4 D $ E 6 F
Question: How many alphabets are there between two symbols?
Solution: Alphabets between symbols: A (between @ and 3), C (between # and 4), D (between 4 and $), F (between 6 and end) → 3 such alphabets (A, C, D)
Answer: 3
Step-by-Step approach to solve the Alphanumeric Series Questions
In this section, we are discussing the step-by-step approach to solving the alphanumeric series. Use these steps to solve the questions in a shorter time period.
- Avoid reading each element slowly. Observe the pattern as a whole and mentally group alphabet, numbers, and symbols. It may not happen on the first go, but eventually you’ll be able to observe the patterns very quickly.
- For complex series, note down positions like 1st, 2nd, 3rd, etc. This prevents confusion during right/left-based questions.
- Many questions are designed with distractions. Identify only the required portion of the series to avoid wasting time in decoding the whole series.
- “If all letters are replaced by the next letters in the alphabet.” This is a type of pattern that you can frequently observe in RRB exams. Practise such variations daily.
- Time yourself when solving Alphanumeric Series sets. A good benchmark is to solve 5 questions within 2 minutes. You may not be able to solve this many questions in the very first practice, but eventually, after some sessions, you will be able to do so.
