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.

8 * 8 - 8 = 56
9 * 9 - 9 = 72
10 * 10 - 10 = 90
11 * 11 - 11 = 110
12 * 12 - 12 = 132.
So the answer should be 13 * 13 - 13 = 156.
150 is wrong
9 * 9 - 9 = 72
10 * 10 - 10 = 90
11 * 11 - 11 = 110
12 * 12 - 12 = 132.
So the answer should be 13 * 13 - 13 = 156.
150 is wrong

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.

56, 72, 90, 110, 132, 150
1st digits = 5, 7, 9, 11, 13, 15.
Last digits = 6, 2, 0, 0, 2, 6.
So 6 is missing at the last digit of 150.
1st digits = 5, 7, 9, 11, 13, 15.
Last digits = 6, 2, 0, 0, 2, 6.
So 6 is missing at the last digit of 150.

@All.
I solve it as;
72-56=16,
90-72=18,
110-90=20,
132-110=22,
150-132=18( here the sequence break )so;
150 is an odd man term.

Here the alternate way is available.... that is
56+16=72
72+18=90
90+20=110
110+22=132
132+24=156
so the 150 is wrong here :)
56+16=72
72+18=90
90+20=110
110+22=132
132+24=156
so the 150 is wrong here :)

It may also be like this, Going on adding 16, 18, 20, 22, 24. So 150 is the wrong answer because it should be replaced by 156.

56+90=146
(146-2)/2= 72
Similarly
(72+110-2)/2= 90.......
(110+150-2)/2=129 but not 132 so 150 is wrong.
(146-2)/2= 72
Similarly
(72+110-2)/2= 90.......
(110+150-2)/2=129 but not 132 so 150 is wrong.

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

72-56=16;
90-72=18;
110-90=20;
132-110=22;
150-132=18; So it is disturbs the sequence of flow.
90-72=18;
110-90=20;
132-110=22;
150-132=18; So it is disturbs the sequence of flow.
