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)
