We have seen that a number series is a grouping of numbers, that follows a particular formula or a given rule. There are several types of number series questions that occur in the IBPS and other banking exams and the Missing Number series is one of it. In the Missing Number series, a series is present with a Missing Number or asking you to predict the last term in it. The candidate has to detect and most of the times calculate the value of this Missing Number. The following article will give you many opportunities to read the concepts, get to know about the various tips and tricks and also see many examples. Let us begin.

Missing Number Series
In the Missing Number series, we see a few examples first. Sometimes, the missing number could be present in the beginning and at other times at the end of the series. As you will see this creates different difficulty levels. The strategy in the missing number series is the same as that of the wrong number series, you have to detect the rule and then use this rule to predict the next number. Following are the tips that can reduce the time consumption to some deal while trying to detect the rule that forms a number sequence:
Pick 2/3 terms to test the rule. That means if you have, say 5 given terms, at least pick three of them to test the rule that you want to predict.
While choosing the terms to test, select the terms that are the easiest to work with. These include terms that a factor of 2, 3, 5 or 10. Test for common rules like sum of the terms, squares, cubes and other formulae.
Let us see some examples that we shall solve. Remember the more you practice, the more you save on time.
