X+x+1+x+2=81

3x+3=81

3x=81-3

3x=78

x=78/3

x=26

x+1=26+1=27

x+2=26+2=28

Take first number = x

then 2nd number = x+1

also 3rd number = x+2

sum of these three numbers =  x + x+1 + x+2

                          x + x+1 + x+2 = 81

                                     3x + 3 = 81

                                           3x = 81 - 3

                                          3x = 78

                                            x = 78 ÷ 3

                                            x = 26

                                       x +1 = 26 + 1

                                              = 27

                                     x + 2 = 26 + 2

                                              = 28

three numbers are 26 , 27 , 28
