Answer 1

Let the first consecutive odd number be X.
then,
Second consecutive odd number will be X + 2
Third consecutive odd number will be X + 4

Smallest consecutive odd number = x
Largest consecutive odd number = X + 4

According to question,
3x-7 = 2(X+4)
3x-7 = 2x + 8
X = 15

Consecutive odd numbers are 15, 17, 19.
