I Hope There's HopeSeries teasers are where you try to complete the sequence of a series of letters, numbers or objects.
Carmela and Jinodel are playing series of numbers. Since it's Carmela's turn she thought of this series:
1, 11, 101, 111, 1001, 1011, _____
If you are Jinodel, what will you answer?
HintThey are not ordinary digits.
AnswerThese extraordinary digits are called Binary System. If you convert these digits to numbers, then it will be
1, 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.
16+8+0+2+1 = 27
