  Given that sum of three consecutive odd numbers sum is 27

  let us suppose consider an odd number as x

  then its next consecutive odd number becomes x+2

  the other consecutive odd number is x+4

  we can write it as x+(x+2)+(x+4)=27

  3x+6=27

  subtract 6 from both sides

  3x+6-6=27-6

  3x=21

  x=21/3

  x=7

  Now x+2=7+2=9

  Now x+2=7+4=11

  Therefore the numbers are 7,9,11.

  Let x be a odd number.

  Let x-2,x,x+2 be the three odd consecutive numbers corresponding to x .

  Given that the sum of three odd consecutive numbers is equal to 27

  That is ,

  (x-2)+x+(x+2) =27

  3x=27

  x=9

  Therefore the three odd consecutive numbers are 7,9,11
