Question

Odd one out 10, 26, 21, 24, 18

Answer 1

To determine the odd one out, we should look for a pattern or a common property among the numbers and see which one does not share that property.
Given the numbers: 10, 26, 21, 24, 18 
Let's analyze: -
 10 is even 
- 26 is even 
- 21 is odd 
- 24 is even 
- 18 is even 
From the above list, four numbers are even and only one (21) is odd. 
So, **21** is the odd one out
