Look at this series: 7, 10,8, 11, 9, 12. Which number do you think will be next?
Correct answer: A. 10
- A. 10
- B. 12
- C. 13
- D. 7
Explanation
Option A is correct since this is a 3 and 2 series. We are adding 3 to 7 so it becomes 10. Then we subtract 2 from 10 so that it becomes 8. Then we add 3 to 8 so it becomes 11. Then we subtract 2 from 11 so it becomes 9. We add 3 to 9 so it becomes 12. Finally, when we subtract 2 from 12, we get 10. Option B is incorrect since it does not give the right answer. Option C is incorrect since it does not give the right answer. Option D is incorrect since it does not give the right answer.
