Answer 2

Odd man out is 91

Solution:

Given that,

We have to find the odd man out

7,  17,  19,  43,  91,  131

Let us analyse the similarity between numbers and find the odd one out

We can see all numbers are prime except 91

Prime numbers : numbers that are divisible only by itself and 1

7 , 17 , 19 , 43 and 131 are prime numbers

But for 91,

$1 \times 91 = 91 \\\\7 \times 13 = 91$

Thus 91 is not a prime number

Thus, odd man out is 91
