Correct option is C
6 7 9 5 6 9 7 6 8 7 6 7 8 6 9 4 6 7 7 6 9 5 7 6 3
We need to count the number of 6’s that are preceded by 7 but not immediately followed by 9.
Step 1: Identify occurrences of "7 6"
We scan the series and locate occurrences where 6 is immediately preceded by 7:
- 7 6 8 → (Not followed by 9)
- 7 6 7 → (Not followed by 9)
- 7 6 3 → (Not followed by 9)
- 7 6 9 → (Followed by 9, not considered)
Step 2: Count the valid cases
Valid occurrences: Three (3) times
Final Answer:
Option C) THREE
