Number Series Practice Questions

Here we deal with the questions in which series of numbers, which are generally called the terms of the series is given. These terms follow a certain pattern throughout the series. Candidates are asked either to find a missing number or to find the one that does not follow the pattern of the series. A number series can be formed by using various characteristics of numbers and by using various types of calculations.

Here we will see how to find a missing term when we are given a sequence of numbers including one or more missing numbers. Such a series follows a pattern, keeping this pattern in mind, we will have to find the missing term.

We shall also encounter questions on how to find the number that does not follow the pattern. In this type of questions, we are given a sequence of numbers. The whole sequence except one number follows a certain rule. You have to find that number which does not follow the rule.
