odd integer +odd integer= even integer

even interger + odd interger = odd integer

1 3 5 7 9 11 13 15 all are odd integer

It doesnt matter what you choose from first two list ,when you add it up, it always give you a even number.

and in the third list, all are odd interger,so when calculate the sum of your integer that you get and the integer

that you choose in third list,you always get a odd integer.

So I think it is impossible to do this.
