Let five consecutives odd numbers are a, a + 2, a + 4, a + 6 and a + 8
let five consecutives even numbers are b, b + 2, b + 4, b + 6 and b + 8
ATQ,
a+ a + 2 + a + 4 + a + 6 + a + 8 = 17× 5
5a + 20 = 85
a = 13
b + b + 2 + b + 4 + b + 6 + b + 8 = 80
5b + 20 = 80
b = 12
Required average = [21+12]/2=16.5
