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.

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.

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

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

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