(D) To find the number of $8$'s that are divisible by both the preceding and succeeding numbers,we examine each $8$ in the series:$1$. The first $8$ (at index $8$): Preceded by $2$,succeeded by $4$. $8$ is divisible by $2$ $(8/2 = 4)$ and $8$ is divisible by $4$ $(8/4 = 2)$. This is a valid $8$.$2$. The second $8$ (at index $10$): Preceded by $4$,succeeded by $4$. $8$ is divisible by $4$ $(8/4 = 2)$. This is a valid $8$.$3$. The third $8$ (at index $14$): Preceded by $2$,succeeded by $2$. $8$ is divisible by $2$ $(8/2 = 4)$. This is a valid $8$.$4$. The fourth $8$ (at index $18$): Preceded by $9$,succeeded by $4$. $8$ is not divisible by $9$. Not valid.$5$. The fifth $8$ (at index $22$): Preceded by $4$,succeeded by $3$. $8$ is not divisible by $3$. Not valid.$6$. The sixth $8$ (at index $25$): Preceded by $2$,succeeded by $4$. $8$ is divisible by $2$ $(8/2 = 4)$ and $8$ is divisible by $4$ $(8/4 = 2)$. This is a valid $8$.$7$. The seventh $8$ (at index $29$): Preceded by $1$,succeeded by $3$. $8$ is not divisible by $3$. Not valid.Thus,there are $4$ such $8$'s.

How many $8$'s are there in the following number series which are exactly divisible by their immediately preceding and also divisible by their immediately succeeding numbers?
$8, 2, 4, 5, 1, 7, 2, 8, 4, 8, 4, 2, 2, 8, 2, 6, 9, 8, 4, 5, 4, 8, 3, 2, 8, 4, 3, 1, 8, 3$
