8, 15, and 16
They’re all less than 25
Range: Max - Min
16 - 8 = 8
Mean: 8 + 15 + 16 = 39/3 = 13
I knew 16-8 would be 8 so I had to find the missing digit in the middle to make the mean 13. I found the missing digit by multiplying 13 by 3 because there are three integers which got me 39. 39 - 8 - 16 = 15.
