There is no solution. For X + (X+1) = 18, 2X = 17 and the answer is not an integer. (8.5)---------But for two consecutive even integers equal to 18 :X + (X+2) = 18 , 2X = 16 and the numbers are 8 and 10.

Divide 54 by three to find the mean (middle number), then subtract one for the low number and add one for the high number. Ex: 54 ÷ 3 = 18. 18 - 1 = 17; 18 + 1 = 19. The three consecutive numbers are 17, 18, and 19.
