Sol
x+(x－1)+(x－2)<25
3x－3<25
3x<28
x<9.34
x<=9
the largest number=9
x+(x－1)+(x－2)<25
3x－3<25
3x<28
x<9.34

let the smallest number=x
so x+(x+1)+(x+2)<25
3x+3<25
3x<28
x<9.333......
x-3<6.333.....
so the largest number maximum is 6
if three numbers are all positive
the largest number minimum is 3
i think the answer might be 3<=number<=6
so x+(x+1)+(x+2)<25
3x+3<25
3x<28
x<9.333......
x-3<6.333.....
so the largest number maximum is 6
if three numbers are all positive
the largest number minimum is 3
i think the answer might be 3<=number<=6
