Number series: Look at this series 7, 10, 8, 11, 9, 12. Which number you think will be next?
Correct answer: A. 10
- A. 10
- B. 13
- C. 7
- D. 12
Explanation
Looking at the given series: 7, 10, 8, 11, 9, 12, we can observe that the pattern involves alternating between two sequences. The first sequence is an increasing pattern: 7, 8, 9, ... The second sequence is also an increasing pattern, but with a difference of 3 between each number: 10, 11, 12, ... By following this alternating pattern, the next number in the series should continue with the first sequence, which means it will be one number higher than the previous number. Therefore, the next number in the series is 10. Hence, option A is the correct answer.
