First, compute the mean: 
Next compute the absolute deviations for each datapoint:
|75-95.555|=20.555
|89-95.555|=6.555
|145-95.555|=49.445
|85-95.555|=10.555
|80-95.555|=15.555
|92-95.555|=3.555
|104-95.555|=8.445
|90-95.555|=5.555
|100-95.555|=4.445
Next we'll take the mean of these deviations:
The mean absolute deviation of your data is 13.8517

One of the numbers is 40 and the other one is 63
confirmation:
63×(2/3)-2=40
and 40+63=103
confirmation:
63×(2/3)-2=40
and 40+63=103
