Let X be the smaller no.
x+2 be the middle.no
x+4 be the greatest no.
x+x+2+x+4=117
3x+6=117
3x=111
x=37
SO,the 3 no, is37,39,41
弟2條一樣
Let X be the smaller no.
x+1 be the middle.no
x+2 be the greatest no.
x+x+1+x+2=111
3x+4=111
3x=108
x=36
所以,這3個數是36,37,38

SO,the 3 no, is37,39,41 SO,the first no. is x=37,the middle no.is x 2=39,the greatest no. is x 4=41 三個連續單數 is37,39,41 弟2條也是:SO,the first no. is x=36,the middle no.is x 1=37,the greatest no. is x 2=38 所以,這3個連續數是36,37,38
