## Tips & Tricks To Solve Alphanumeric Questions

There are a variety of types in which questions may be asked for the alphanumerical series. These include:

**Missing Series:**Where a series of alphabets and numbers may be given a particular pattern and candidates may be asked to fill in the blank space with the required element**Alphabet-Number-Symbol:**These questions may also be asked in a format where a series with alphabets, number and different types of symbols (like &, *, $, etc.) may be given, and questions may be asked based on them**Only Alphabetic Series:**Series with either missing element or questions with sub-parts may be asked which comprise only English Alphabets and no numbers, set in a specific pattern**Only Numerical Series:**Series comprising only numbers, set in a specific pattern may be asked the exam. Questions based on this type may be asked in the form of rearrangement of numbers or digits with the number in ascending, descending or any other order.

Given below are a few tips and tricks that may help you solve the questions based on the alphanumeric series:

- In pattern-based series, first, analyse alphanumeric series given to you and try to crack the pattern that is being followed. Mostly the pattern may involve change is succeeding or preceding terms of either the number or the alphabet
- In abrupt series, which include number-symbol-alphabet, mostly no pattern is followed. Candidates need to move to the sub-part of the questions and straightaway answer them
- Ensure that for missing number series, you recheck the entire series after finding an answer, to ensure that no error has been made
