13, 15, 17, 19
It is {13, 15, 17, 19}.
there are 3.... 7,9,11
No odd whole numbers have 12 as a factor. 1 and 3 are odd numbers that are factors of 12.
13, 15, 17 and 19
13 if you include the '75', 12 if you don't.
The numbers between 10 and 20 that are not prime are 12, 14, 15, 16 and 18. So 15 is the odd number and the rest are even numbers.
They are: 5 7 9 and 11 which makes four of them
