The sum is 3640.
It is: 11+13+17+19+23+29 = 112
The sum of the five odd numbers between 10 and 20 is: sum = 5 x (11 + 19) / 2 = 75.
38
Because the sum of its proper divisors is less than 19.
34
13 + 17 = 30
The prime factors of 34 are 2 and 17, and 2 + 17 = 19.
They add up to 112

38
Because the sum of its proper divisors is less than 19.
It cannot make the sum because: if the numbers are in odd quantity there sum is always a odd number
