Answer 1

Here is your answer
Let the number be X
So X+X+1+X+2=21
3X+3=21
Therefore,3X=21-3
3X=18
So, X=18/3
X= 6

THEREFORE THE NUMBERS ARE 6,7,8

Answer 2

Let the three consecutive numbers be x , x+1 , x+2

x + x+ 1+x+2 = 21

3x +3 =21

3x = 18

x=6

Therefore, the three consecutive numbers are 6 , 7 and 8
