How to Solve Alphanumeric Series
Identify the Pattern
Look for any consistent 
increase or decrease in 
numbers or a specific 
alphabetical pattern (e.g., every 
alternate letter, every third 
number).
Check Number and Letter 
Movement
Numbers may follow arithmetic 
or geometric progression, and 
letters might follow the 
alphabetical order or a set 
interval.
Apply the Rule
Use the pattern to find the 
missing number or letter.

Example 1 3 Identifying 
the Next Element
Example
S e r i e s: A1, B2, C3, D4, ____
Solution
The series follows an incremental pattern where 
both the letter and number increase by 1. The next 
element in the series would be E5.
