Correct answer
3
Why this answer is correct
Given: (Left) 3 2 2 5 8 4 9 4 8 (Right)
Now,
Even numbers which are immediately preceded by an odd number and also immediately followed by an even number.
So, needed pattern is: Odd - Even - Even
(Left) 3 2 2 5 8 4 9 4 8 (Right)
So, total valid even numbers = 3
Hence, the correct answer is Option 2.
