Answer 1

Answer:

81

Step-by-step explanation:

9= 8+1= 81-63= 18 (reversed)

7+2= 72-63= 9 (Not reversed)

6+3= 63-63= 0 (Not reversed)

5+4= 54-63= -9 (Not reversed)

4+5= 45-63= - 18 (Not reversed)

3+6= 36-63= -27 (Not reversed)

2+7= 27-63= -36 (Not reversed)

1+8= 18-63= -45 (Not reversed)

81 is only reversed it is the answer.
