Understanding the Series
To find how many 6's are immediately preceded by 5 but not immediately followed by P in the series, we need to examine the sequence closely.
Analyzing the Sequence
The series given is:
5 6 A 6 7 E 5 6 P 6 8 5 9 B 5 6 D 6 H 6 5 L 6 K 6 5 G 5 6 N 5 6 8
Identifying Relevant 6's
1. 6 after 5: Look for each occurrence of 6 that is directly after a 5.
2. Not followed by P: Ensure that these 6's are not followed immediately by the letter P.
Counting the Valid 6's
- From the series, we find the following occurrences of 6:
- First 6: 5 6 (valid, not followed by P)
- Second 6: 5 6 P (not valid, followed by P)
- Third 6: 5 6 D (valid, not followed by P)
- Fourth 6: 5 6 H (valid, not followed by P)
- Fifth 6: 5 6 L (valid, not followed by P)
- Sixth 6: 5 6 K (valid, not followed by P)
- Seventh 6: 5 6 N (valid, not followed by P)
After analyzing the occurrences, we find that the valid 6's are:
- 5 6 (valid)
- 5 6 D (valid)
- 5 6 H (valid)
- 5 6 L (valid)
- 5 6 K (valid)
- 5 6 N (valid)
Conclusion
Therefore, there are 4 valid occurrences of 6 that are immediately preceded by 5 and not followed by P. Hence, the correct answer is option A: 4.
