Number Series I – Number Series Tricks to solve Questions

In this post, we will discuss examples of questions from number series and solve them using number series tricks to save time in SSC CGL Exam
Number Series Tricks
Number Series Questions are numerical logical questions, frequently asked in SSC CGL Exam. In number series, a sequence is given from which we have to deduce a pattern. Then that pattern is used to predict the missing number in the series.The difficulty level of number series questions can increase in two ways; the logic behind the sequence becomes less trivial, therefore demanding attention and creativity, or the missing number is positioned at an early stage where you can figure out the missing number by only looking at the previous numbers in the sequence. These number series questions are little tricky but they can easily be solved by using number series tricks.

In this post, we have discussed few questions and have solved them using Number Series tricks to save time in SSC CGL Exam. 

Example 1: Questions Solved using Number Series Tricks

Question:  1, 2, 3, 4, 5, 6, ?
Solution:           
To solve this number series question, we need to figure out the logic behind the series in order to find the missing number.

We can make out that every number is one more than the previous number.
Hence, 6 + 1 = 7
6 + 1 = 7
Therefore, 7 is the missing number.
