Hey...!!!
Let the numbers be x, x + 2 and x + 4
So,
X + x + 2 + x + 4 = 21
3x + 6 = 21
3x = 21 - 6
3x = 15
X = 15/3
X = 5
So, numbers are
5
( 5 + 2 ) = 7 and,
( 5 + 4 ) = 9
Hope it helps...!!!

let x be the required first odd number , (x+2) be the second odd no. and (x+2+2) be the third odd number.
x+(x+2)+(x+2+2)=21
........(solve it)
OR,
let (x-2), x and (x+2) be the three odd consecutive numbers.
(x-2)+x+(x+2)=21
The answer is 5,7 and 9.
x+(x+2)+(x+2+2)=21
