Answer:

To find the number of 7s that are preceded by 9 and followed by 6, we need to analyze the given number series and identify the specific pattern.

Observations:
- The number series starts with 5 and follows a pattern of increasing and decreasing numbers.
- The first few numbers in the series are increasing - 5, 7, 8, 9.
- After the number 9, the series starts decreasing - 7, 6, 5, 3, 4, 2.
- Then, the series again starts increasing - 6, 8, 9.
- After 9, the series decreases again - 7, 5, 2, 4, 6, 2.
- Finally, the series starts increasing again - 9, 7, 6, 4, 7, 8, 9, 7, 6.

Analysis:
- From the given observations, we can see that the number 7 is preceded by the number 9 and followed by the number 6 only twice in the series.

Calculations:
- The 7s that are preceded by 9 and followed by 6 are:
1. 9 7 6
2. 6 7 6

Conclusion:
- Therefore, there are a total of 2 7s that are preceded by 9 and followed by 6 in the given number series.

Answer: c) 3
