Answer:
To find the number of times an even number is preceded by an odd number in the given series, we need to carefully observe the sequence and identify the pattern.
Observation:
- The series starts with the numbers 5, 7, 8, 9, which appear to be in ascending order.
- After the number 9, the series takes a downward trend and starts repeating a pattern of numbers.
- The pattern is as follows: 7, 6, 5, 3, 4, 2, 6, 8, 9, 7, 5, 2, 4, 6, 2, 9, 7, 6, 4, 7, 8, 9, 7, 6.
- As we can see, the pattern repeats itself after the number 6.
Analysis:
- We need to find the even numbers in the given series and check if they are preceded by an odd number.
- Let's list down the even numbers and their preceding numbers:
- 8 is preceded by 7 (odd)
- 6 is preceded by 9 (odd)
- 4 is preceded by 2 (even)
- 2 is preceded by 5 (odd)
- 6 is preceded by 4 (even)
- 8 is preceded by 7 (odd)
- 6 is preceded by 9 (odd)
- 4 is preceded by 6 (even)
- 6 is preceded by 7 (odd)
Counting:
- From the above analysis, we can observe that an even number is preceded by an odd number 6 times in the given series.
Therefore, the correct answer is option 'D' - 6.
