anonymous · Answer

consecutive even intergers means thing like 2,4,6,8 etc.. so 3 consecutive intergers that equal 156 would be 50,52, and 54. the least being 50

anonymous · Answer

x+x+2+x+4=156
x=50

lalaly · Answer

since they are even numbers they should be 2, 4 , 6 ,... so there is a difference of two between two consecutive numbers
so 
n+(n+2)+(n+4)=156
3n+6=156
3n=150
n=50

anonymous · Answer

Let x be the middle integer.  Solve the following for x:
(x - 2) + x + (x + 2) =156
3x = 156
x = 52
x-2 = 50, the smallest
