This puzzle is made by me. In the below diagram you can see there are two missing numbers; you need to fill them with the appropriate numbers.
The missing numbers are

There are 3 types of numbers. Outer, Middle and Inner. The outer number is sum of the middle number on the same side and the inner number on the opposite side.
The outer number 14 is the sum of 27 and -13. And 41 is the sum of 25 and 16
