Carmela and Jinodel are playing series of numbers. Since it's Carmela's turn she thought of this series:

If you are Jinodel, what will you answer?
1, 11, 101, 111, 1001, 1011, _____
If you are Jinodel, what will you answer?
Hint
They are not ordinary digits.Answer
These extraordinary digits are called Binary System. If you convert these digits to numbers, then it will be1, 3, 5, 7, 9, 11, so what's the next number... 13 or 1101.
To change Binary system to numbers, the procedure is:
1. You read numbers from right to left.
2. You start of with 1 then multiply it by 2 in every next digit.
3. If the corresponding binary digit is 0 then that is expelled.
4. Then add the digits together.
Ex.
11011
16+8+0+2+1 = 27
