Question

Find three consecutive number of 81

Answer 1

Step-by-step explanation:

let the three consecutive number are:

x , x+1 , x+2

x+x+1+x+2 =81

3x+ 3=81

3x= 81-3

3x=78

x=78/3

x=26

The first number x =26

the second number x+1 =26+1=27

the third number x+2=26+2=28

Answer 2

26,27,28

Step-by-step explanation:

Let the unknown no be x. Then the next three consecutive no is x,(x+1),(x+2)

equation:-

x+(x+1)+(x+2)=81

x+x+1+x+2=81

3x+3=81

3x=81-3

x=79/3

x=26

1st number =26

2nd no.=x+1

=26+1

=27

3rd no.=x+2

=26+2

=28
