# 30 + Series Questions and Answers | Nonverbal Reasoning

In India, the Non Verbal Reasoning portion of competitive exams frequently includes questions on number series. These kinds of questions consist of a succession of numbers and a blank that needs to be filled in. It is your job to identify the pattern between the numbers, their predecessor, and their successor to get the solution to the blank. Although it might seem easy, it can be difficult to understand the reasoning behind the pattern.

We have included practice questions below so that applicants can get ready for these exams and do well. The blog includes questions as well as some approaches to answering a number series problem.

## Tips and Tricks to Solve Number Series Questions

The Easiest way to approach number series questions is to observe the difference between the various terms. Here are some methods and tips you can use to solve number series questions:

• If you notice a constant difference between the different numbers, it shows that the question belongs to the series with a constant degree category.
• If you observe the difference between the various numbers it is either increasing or decreasing, then the question belongs to either the series with an increasing difference or the series with decreasing difference respectively.
• In case, you are not able to spot an increasing or decreasing difference between the numbers, try to divide the 2nd term of the series with the first, the 2nd term with the 3rd term, and so on. If the answer to the constant division comes as the same number, then this question belongs to the product series.
• In case, none of the above approaches works, you can write every term of the question as to the multiplication of 2 factors and try to spot a pattern between the terms.
• If you are not able to spot a pattern and the difference between the terms is decreasing or increasing at an accelerated rate, you can try for the square/cube series.
