What is a Number Series?<\/strong><\/h2>\n\n\n\n

A series of numbers that are sequenced in a pattern, or following a particular rule. You have to either find out the missing number or identify the wrong number in the given set. This is to check the candidate’s ability to solve problems with quick accuracy, and also tests pattern recognition that will ultimately help the candidates to find loopholes in the system. <\/p>\n\n\n\n

Common Patterns in SBI PO Number Series<\/strong><\/h2>\n\n\n\n

Certain common patterns are usually asked in SBI PO Number series. They are given in the table below.<\/p>\n\n\n\n

Tips to Solve Number Series Quickly<\/strong><\/h2>\n\n\n\n

To stay ahead in the competition, one needs to master speed along with accuracy. To solve number series quickly, here are a few tips given below.<\/p>\n\n\n\n

Observe the Gap Between Numbers<\/strong><\/h3>\n\n\n\n

Start by observing the pattern between the consecutive numbers. Check whether the pattern is based on addition, subtraction, or a difference of squares\/cubes.<\/p>\n\n\n\n

Check for Multiplication\/Division<\/strong><\/h3>\n\n\n\n

If the difference between the numbers is increasing or decreasing rapidly, then check for multiplication and division logic. Example- Series: 3, 6, 18, 72, 360,?<\/strong><\/p>\n\n\n\n

Step 1: Observe differences<\/strong><\/p>\n\n\n\n
