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:

  1. 7 6 8 → (Not followed by 9)
  2. 7 6 7 → (Not followed by 9)
  3. 7 6 3 → (Not followed by 9)
  4. 7 6 9 → (Followed by 9, not considered)

Step 2: Count the valid cases

Valid occurrences: Three (3) times

Final Answer:

Option C) THREE
