(B) We need to find even numbers $E$ such that $E$ is divisible by the preceding number $P$ $(E \pmod P = 0)$ and $E$ is $NOT$ divisible by the following number $F$ $(E \pmod F 
eq 0)$.Let's analyze the sequence: $3, 8, 4, 1, 5, 7, 2, 8, 3, 4, 8, 9, 3, 9, 4, 2, 1, 5, 8, 2$$1$. $8$: Preceded by $3$ (not divisible).$2$. $4$: Preceded by $8$ (not divisible).$3$. $2$: Preceded by $7$ (not divisible).$4$. $8$: Preceded by $2$ ($8/2 = 4$,divisible). Followed by $3$ $(8/3 eq 	ext{integer})$. Condition met.$5$. $4$: Preceded by $3$ (not divisible).$6$. $8$: Preceded by $4$ ($8/4 = 2$,divisible). Followed by $9$ $(8/9 eq 	ext{integer})$. Condition met.$7$. $4$: Preceded by $9$ (not divisible).$8$. $2$: Preceded by $4$ (not divisible).$9$. $8$: Preceded by $5$ (not divisible).$10$. $2$: Preceded by $8$ (not divisible).The numbers satisfying the condition are $8$ (at index $8$) and $8$ (at index $11$).Thus,there are $2$ such numbers.

In the following number sequence,how many such even numbers are there which are exactly divisible by its immediate preceding number but not exactly divisible by its immediate following number?
$3, 8, 4, 1, 5, 7, 2, 8, 3, 4, 8, 9, 3, 9, 4, 2, 1, 5, 8, 2$
