An odd number is written 2n+1 with n any number
(2n1+1)+(2n2+1)+...+(2n9+1) = 2(n1+n2+...+n9)+9 = 50 is not possible as
2(n1+n2+...+n9) = 41 is not possible with integers

The sum of 9 odd numbers will be odd and so cannot be 50.
Oh, dude, to find 9 odd numbers that add up to 50, you can start with 1 and keep adding 2 until you reach 17. So, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 = 50. Easy peasy, right? Like, who needs even numbers anyway?
There is no way without playing silly games. Each of the numbers in the list is odd. The sum of five odd numbers must be odd and therefore, cannot be 50. There is no way without playing silly games.

1+3+5+7+9+7+9+9
As long as more than one mathematical operator is allowed then 50 can be formed in several ways from the first ten odd numbers - i.e. those from 1 to 19. (7 x 17) - 13 - 9 - 5 = 77 - 27 = 50.
