well arithmetic mean is adding/subtracting the same number..

jim766 · Answer

first determine how far apart the numbers are
12 - (-13)  = 25 

then since you what 4 means, take 25 and divide by 4+1 or 5

25/5 = 5

-13 +5   
-8   + 5
-3   +5
2     +5
7      +5
12 

  -13,      -8, -3, 2, 7,     12 
                these are the
                4 means
