The last digits are 6, 2, 0, 6, 2, 0.
Hence 110 is the odd no.

All are divisible by 3, except 110. So 110 is odd one.

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.

If we take 6 as divisor, then 110 will be answer. Because all others are divisible by 6.

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.

You can even think this way.
1) The first two digits are following odd numbers.
i.e. 5+2=7, 7+2=9...
2) The last digit is some what like this.
6, 2, 0, 0, 2, 6...
But 150 didn't satisfy 2nd rule. I think this is crazy thought.

72-56=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.

According to the differences of the respective numbers next term should be 156.
But according to the given explanation the next term should be 172.
Really confusing.

The difference between the 2 successive numbers ie,72-56=16,90-72=18,110-90=20,132-110=22,{150-132=18}which has to be 24.so 150 is the wrong no.
