What three consecutive integers equal 81

The consecutive integers: n, n+1, n+2

That sum to 81:

n+n+1+n+2=81 combine like terms on left side

3n+3=81 subtract 3 from both sides

3n=78 divide both sides by 3

n=26

So the three numbers are 26, 27, and 28.

81 / 3 = 27

so middle number = 27

the other 2 are 26 and 28

answer

26, 27, 28 are three consecutive integers equal 81
