Find Three Consecutive Numbers Whose Sum Is 84? | TIRLA ACADEMY

Let the first number be x

The second will be (x+1)

Third number = (x+2)

Their sum is = 84

So,

x+(x+1)+(x+2) = 84

3x+3=84

3x=84-3

3x=81

x=81/3

x=27

x=27, (x+1)=28, (x+2)=29

27, 28, and 29 are three consecutive numbers whose sum is 84.
