Odd Man Out questions are one of the easiest topics in the Logical Reasoning section. The following article covers Odd Man Out questions to aid in the improvement of your conceptual comprehension. Creating a methodical way to answer these questions is also beneficial. This could entail examining the distinctions between the things or seeking patterns or commonalities in the objects.

**Quick Tips and Tricks for Odd Man Out Questions: **

- Find similarities between a list of things and identify the odd one.
- Look for patterns and connections.
- Discard anything that doesn’t fit.
- Use logic to narrow down solutions.

It’s crucial to properly understand the Odd Man Out questions to master them.

Series:

The given terms or elements in a series follow a definite law that cannot be generalized. To understand the relationship between the numbers that make up the series, one must identify the specific relationship between them. Such a series can be formed by addition, subtraction, multiplication, division, or transposition of terms. The type of questions asked about the series may vary and depend on these factors.

**1) Odd number/Even number/Prime numbers**

The series may consist of odd numbers /even numbers or prime numbers except one number, which will be the odd man out. Hence, before solving numerical on this topic must revise all basic concepts.

**2) Perfect squares/Cubes:**

Squares: 9, 16, 49, 81 ….

Cubes: 27, 64, 125, 216 ….

**3) Multiple of numbers:**

The series contains numbers which are multiple of different numbers.

Example: 4, 8, 12, 16, 20…..

**4) Difference or sum of numbers:**

The difference between two consecutive numbers may increase or decrease

5) Cumulative series:

In this type, the third number is the addition of previous two numbers.

Example: 2, 4, 6, 10, 16, 26 ……

6) The middle digit is the sum of other two digits.

Example: 165, 121, etc

7) Power series:

In this type, the terms are defined on the basis of powers of numbers; the number may be expressed in the form of n3 – n.

Example:

If n = 4, n3 – n = 60

If n = 5, n3 – n = 120…

Series: 60, 120, 210, 336 …

8) The series of numbers may follow different sequence as shown below:

(n2 – 1), (n2 + 1), (n2 – n), (n3 – n), (n2 – n + 1), (n2 – n – 1), etc
