It is 14/20 or 7/10.
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.
The sum of the five odd numbers between 10 and 20 is: sum = 5 x (11 + 19) / 2 = 75.
No. -_-

Yes - every prime number except for 2 is odd - including the primes between 10 and 20, namely 11, 13, 17, and 19.
The sum of the five odd numbers between 10 and 20 is: sum = 5 x (11 + 19) / 2 = 75.
of course... there is sometimes a odd number of 10's
20 is an even number.
No. -_-
what number is next in the sequence: 10,20,30,20,(? 30
