23 +1² = 24

Given,
Series,
23, 24, 28, 37, 53, 81, 114.
To find,
The number that doesn't belong to the series.
Solution,
It can be seen that in the given series,
The difference between the 2nd and the 1st number is,
24 - 23 = 1. That is 1².
And that between 3rd and the 2nd number is,
28 - 24 = 4. That is 2².
Following the same process, we can see that logic for the given series is as follows,
23 + 1² = 24,
24 + 2² = 28,
28 + 3² = 37,
37 + 4² = 53,
53 + 5² = 78, and,
78 + 6² = 114.
So, it can be seen that, following the above logic, it should be 78 in place of 81.
Therefore, the number 81 does not belong to the given series.
