(C) We need to find numbers that satisfy the condition: (Preceded by $6$) $AND$ ($NOT$ followed by $4$).Let's analyze the series: $3, 8, 6, 8, 4, 2, 6, 9, 8, 4, 6, 8, 4, 8, 6, 2, 6, 8, 4, 8$$1$. Look for $6$ in the series:- The first $6$ is followed by $8$ (not $4$). This satisfies the condition. The number is $8$.- The second $6$ is followed by $9$ (not $4$). This satisfies the condition. The number is $9$.- The third $6$ is followed by $8$ (not $4$). This satisfies the condition. The number is $8$.- The fourth $6$ is followed by $2$ (not $4$). This satisfies the condition. The number is $2$.- The fifth $6$ is followed by $8$ (not $4$). This satisfies the condition. The number is $8$.Wait,let's re-examine the sequence carefully: $3, 8, 6, 8, 4, 2, 6, 9, 8, 4, 6, 8, 4, 8, 6, 2, 6, 8, 4, 8$- $6, 8$ (followed by $4$): No.- $6, 9$ (followed by $8$): Yes ($9$ is the number).- $6, 8$ (followed by $4$): No.- $6, 2$ (followed by $6$): Yes ($2$ is the number).- $6, 8$ (followed by $4$): No.There are $2$ such numbers: $9$ and $2$.

How many such numbers are there in the following series,each of which is immediately preceded by $6$ but not immediately followed by $4$?
$3, 8, 6, 8, 4, 2, 6, 9, 8, 4, 6, 8, 4, 8, 6, 2, 6, 8, 4, 8$
