✔ 最佳答案
w(代數)係喺3個連續數(eg.1,2,3 7,8,9)之中最細的,試找出他們相加後的總和2007-09-23 12:37:46 補充：
加埋下面d答案,變成解題加答案..我以為你只係解題唔駛計,不過咁易你都識啦let w is the smallest among three consecutive numbersthe second number = w + 1the third number = w + 2therefore,THe sum = w + (w + 1) + (w + 2) = 3w + 3 = 3 (w + 1)

let w is the smallest among three consecutive numbers
the second number = w + 1
the third number = w + 2
therefore,
THe sum = w + (w + 1) + (w + 2) = 3w + 3 = 3 (w + 1)
the second number = w + 1
the third number = w + 2
therefore,
THe sum = w + (w + 1) + (w + 2) = 3w + 3 = 3 (w + 1)
