odd numbers are arithenatic sequence .

sum of the three consecutive odd numbers = 87

let 'x' be the middle number ,

x-2,x,x+2 are the numbers ,

x-2+x+x+2 = 87

3x = 87

x = 87/3

x = 29

numbers :

x+2=31

x-2=27

x=29

numbers = 27,29,31

checking is it is correct ,

27+29+31=87

odd numbers : 27,29,31
