Answer:
17, 19, 21
Step-by-step explanation:
let the 3 consecutive odd numbers be n, n + 2 and n + 4 , then
3n = 2(n + 4) + 9 ( 3 times smallest is 9 more than twice the largest )
3n = 2n + 8 + 9
3n = 2n + 17 ( subtract 2n from both sides )
n = 17
n + 2 = 17 + 2 = 19
n + 4 = 17 + 4 = 21
The 3 numbers are 17, 19, 21
