The answer is a, 11 5. You alternate between entries increasing by 2 and entries that decrease by 1. So looking at 1 3 5 7 9.....the next entry is 11. Similarly, 10 9 8 7 6....the next entry is 5. So 11 5.

11 5.
Put the numbers on two rows, by placing every second number on the upper row, and the other numbers on lower row.
1 3 5 7 9
10 9 8 7 6
Now you should see clearly that the upper row misses an 11 and the lower row misses a 5.
