Let the pair of consecutive odd positive integers be x, x + 2 such that both are greater than 15 and their sum is less than 50
x > 15 and  x + (x + 2) < 50
x > 15 and  2x + 2 < 50
x > 15 and  2x < 48
x > 15 and  x < 24
15 < x < 24 and x is odd
x = 17, 19, 21, 23 and therefore, x + 2 = 19, 21, 23, 25
Possible pairs are (17, 19), (19, 21), (21, 23), (23, 25)
