Their average is 22 and their difference is 9 so use 22 and 9 13*31 = 222 - 92 = 484 - 81 = 403
81 - 50 = 31 50 - 19 = 31
1
It is: 134+110+81+101 = 426 and 426/4 = 106.5 which is the average
The average is 82.
31 + 26 + 24 = 81 / 3 = 27 To find the above average, add the the three numbers together, then divide by 3
-112
31 + 50 = 81.
14. 14*8-81=31. or (31+81)/8 = 14
Their average is 22 and their difference is 9 so use 22 and 9 13*31 = 222 - 92 = 484 - 81 = 403
If you mean: 53 81 41 47 and 31 then 81 is a composite number while all the rest are prime numbers
81 - 50 = 31 50 - 19 = 31
For the values: 81, 31, 17 the LCM is: 42,687
1
It is: 134+110+81+101 = 426 and 426/4 = 106.5 which is the average
The average is 82.
Prime: 13, 23, 31 Composite: 15, 18, 51, 66, 81
