Types of Number Series Questions Asked in IBPS RRB Clerk<\/strong><\/h2>\n\n\n\n

Let\u2019s look at the most common types of number series questions you\u2019ll see in the exam. Each type has a different logic, and once you understand the pattern, solving becomes easy.<\/p>\n\n\n\n

1. Arithmetic Series (Addition\/Subtraction)<\/strong><\/h3>\n\n\n\n

These series follow a fixed addition or subtraction pattern.<\/p>\n\n\n\n

Example:<\/strong>
<\/strong>2, 5, 8, 11, 14, ?
Logic:<\/strong> Add 3 each time.
Answer:<\/strong> 17<\/p>\n\n\n\n

These are the simplest types. Just check the difference between numbers. If it\u2019s constant, it\u2019s an arithmetic series.<\/p>\n\n\n\n

2. Multiplication or Division Series<\/strong><\/h3>\n\n\n\n

Here, each number is multiplied or divided by a fixed number.<\/p>\n\n\n\n

Example:<\/strong>
<\/strong> 2, 4, 8, 16, 32, ?
Logic:<\/strong> Multiply by 2
Answer:<\/strong> 64<\/p>\n\n\n\n

These series grow fast. Look at how the numbers increase or decrease. If the change is big, try multiplication or division.<\/p>\n\n\n\n

3. Mixed Operations (Add + Multiply)<\/strong><\/h3>\n\n\n\n

These series use a mix of operations like adding and multiplying.<\/p>\n\n\n\n

Example:<\/strong>
<\/strong> 2, 5, 10, 17, 26, ?
Logic:<\/strong> Add 3, 5, 7, 9\u2026
Answer:<\/strong> 37<\/p>\n\n\n\n

Here, the difference between numbers increases in a pattern. Check how the gap changes and apply the logic.<\/p>\n\n\n\n

4. Square or Cube Series<\/strong><\/h3>\n\n\n\n

These series are based on squares or cubes of numbers.<\/p>\n\n\n\n

Example:<\/strong>
<\/strong> 1, 4, 9, 16, 25, ?
Logic:<\/strong> Squares of 1, 2, 3, 4, 5\u2026
Answer:<\/strong> 36<\/p>\n\n\n\n

If the numbers look familiar, try checking if they are squares or cubes. These are easy to spot with practice.<\/p>\n\n\n\n

5. Alternating Series<\/strong><\/h3>\n\n\n\n

In these series, two patterns run in alternate positions.<\/p>\n\n\n\n

Example:<\/strong>
<\/strong> 2, 4, 6, 10, 12, 14, ?
Logic:<\/strong> Two series: Even numbers and +4 pattern
Answer:<\/strong> 18<\/p>\n\n\n\n

Check if every second number follows a different rule. These are tricky but easy once you spot the pattern.<\/p>\n\n\n\n

6. Wrong Number Series<\/strong><\/h3>\n\n\n\n

Here, one number in the series is wrong. You have to find it.<\/p>\n\n\n\n

Example:<\/strong>
<\/strong>3, 6, 12, 24, 50, 96
Logic:<\/strong> Multiply by 2 \u2192 3\u00d72=6, 6\u00d72=12, 12\u00d72=24, 24\u00d72=48 (not 50)
Answer:<\/strong> 50 is wrong<\/p>\n\n\n\n

These questions test your observation. Look for the number that breaks the pattern. Solve more wrong number series questions. Know more about wrong number series from here!<\/a><\/p>\n\n\n\n

7. Odd One Out Series <\/strong><\/h3>\n\n\n\n

Odd one out questions are a special type of number series where one number doesn\u2019t follow the pattern. <\/p>\n\n\n\n

Solved Example <\/strong><\/p>\n\n\n\n

Question:
<\/strong>3, 6, 12, 24, 50, 96<\/p>\n\n\n\n
