No, @Sushrita.

56 is also not divisible by 6.

72-56 = 16
90-72 = 18
110-90 = 20 132-110 = 22.

So, the next term is 132 + 24 = 156.
Therefore option [D] is the answer.

@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.

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

56 72 90 110 132 150

The logic is +16, +18,+20,+22,+24.
56 + 16 = 72,
72 + 18 = 90,
90 + 20 = 110,
110 + 22 = 132,
132 + 24 = 156.
So "150" is wrong.

I have added 16 for the 1st two numbers, followed by 18 and so on.
For 132, we should add 24, and then the number should be 156. But the number mentioned was 150.
So 150 is an odd number.
