The average is the sum of variables divided by their count. For an instance:
x = 6
y = 102
z = 9
The average will be
( 6 + 102 + 9 ) / 3 = 117 / 3 = 39
12 + 10 + 11 equals 33

17 + 11 + (25-12) = 17 + 11 + 25 - 12 = 41.
4x2 plus 3=11
This is related to an x + (x+1) + (x+2) function, in which case x equals 10. 10+11+12 is equal to 33.
12 + 10 + 11 equals 33
