Given 56, 72, 90, 110, 132, 150.
Now lets check their squares 56 = 7 square (49) + 7 = 56.
Likewise in case of 72 = 8 square (64) + 8 = 72.
But in case of 150 = 12square (144) + 12 = 156.
So 150 is an odd number to be outed friends.

All the numbers except 110 are divisible by 3. And hence in my opinion 110 is wrong option.

Given 56, 72, 90, 110, 132, 150.
7 * 8 = 56.
8 * 9 = 72.
9 * 10 = 90.
10 * 11 = 110.
11 * 12 = 132.
12 * 13 = 156.
From the above explanation, 150 is incorrect. So it is odd one.
7 * 8 = 56.
8 * 9 = 72.
9 * 10 = 90.
10 * 11 = 110.
11 * 12 = 132.
12 * 13 = 156.
From the above explanation, 150 is incorrect. So it is odd one.

60 - 4 = 56,
80 - 8 = 72,
100 - 10 = 90,
100 + 10 = 110,
120 + 12 = 132.
80 - 8 = 72,
100 - 10 = 90,
100 + 10 = 110,
120 + 12 = 132.

56 + 16 = 72
72 + 18 = 90
90 + 20 = 110
110 + 22 = 132
132 + 18 = 150
So, 150 is wrong.
72 + 18 = 90
90 + 20 = 110
110 + 22 = 132
132 + 18 = 150
So, 150 is wrong.

72 + 60 = 132
90 + 60 = 150
56 + 60 = 116
But given is 110, this is also a type of series and 110 is also an answer.
So it's a multiple type answer.
90 + 60 = 150
56 + 60 = 116
But given is 110, this is also a type of series and 110 is also an answer.
So it's a multiple type answer.

All the number except 110 are exactly divisible by 3 so 110 is also a correct answer.

7 2 -56 = 16
90 - 72 = 18
110 - 90 = 20
132 - 110 = 22
150 - 132 = 18.
So, 150 is wrong.
90 - 72 = 18
110 - 90 = 20
132 - 110 = 22
150 - 132 = 18.
So, 150 is wrong.

@ALL.
5 + 2 = 7
6 - 4 = 2
72
7 + 2 = 9
2 - 2 = 0
90
9 + 2 = 11
0 - 0 = 0
110
11 + 2 = 13
0 - 2 = - 2
132
13 + 2 = 15
- 2 - 4 = - 6
156
NOTE : JUST IGNORE THE MINUS ( - ) SYMBOL.
5 + 2 = 7
6 - 4 = 2

110 can also be answer of this. As all numbers except 110 are divisible by 6. So it can be 110. Isn't it?
