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

Raj Verma said:   9 years ago
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.

56 + 16 = 72
72 + 18 = 90
90 + 20 = 110
110 + 22 = 132
132 + 18 = 150

So, 150 is wrong.

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

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.

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.

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.

56 is not divisible by 6 & 3.

150 disturbs the series of adding +16, +18, +20, +22, +24.

The right no is 154.

So 150 is the odd number.

If logic of numbers divisible by 3 is applied then 110 becomes odd.

Sandip Pradhan said:   9 years ago
The numbers are 7 x 8, 8 x 9, 9 x 10, 10 x 11, 11 x 12, 12 x 13.

So, 150 is wrong.
