(8 + 70)/2 = 39

the answer is 5

2
The number is 80
Any number from 2 to 8.
Just subtract the lowest number from the greatest number. For example, the distance between 3 and 8, is 8 - 3 = 5 units, the distance between -2 and 3, is 3 - (-2) = 3 + 2 = 5 units, the distance between -4 and -2, is -2 - (-4) = -2 + 4 = 2 units.
1, 2, 4, 8
The average of 8 and 4 would be 6 (8+4)/2=6
To find it, take 1/2 of their sum.1/2 (8 + 54) = 1/2 (62) = 31.Note:Some people call it the "number that's half way between" 8 and 54.Others call it the "average" of 8 and 54.
