(A) We need to find the occurrences of the patterns $9, 1, 8$ or $8, 1, 9$ in the given series.The series is: $2, 1, 9, 8, 1, 9, 8, 3, 7, 1, 9, 7, 8, 1, 2, 9, 1, 9, 8, 1, 8, 2, 1, 2$.Let's scan the series:$1$. $2, 1, 9, 8, 1, 9, 8, 3, 7, 1, 9, 7, 8, 1, 2, 9, 1, 9, 8, 1, 8, 2, 1, 2$Scanning for $9, 1, 8$ or $8, 1, 9$:- At index $4, 5, 6$: $1, 9, 8$ (No,$1$ is not in the middle)- At index $16, 17, 18$: $9, 1, 9$ (No)- At index $17, 18, 19$: $1, 9, 8$ (No)- Let's re-examine the sequence: $2, 1, 9, 8, 1, 9, 8, 3, 7, 1, 9, 7, 8, 1, 2, 9, 1, 9, 8, 1, 8, 2, 1, 2$- Looking for $9, 1, 8$ or $8, 1, 9$:- Sequence segment: $... 9, 1, 9, 8 ...$ (No)- Sequence segment: $... 9, 1, 8 ...$ (Found at the end: $9, 1, 8$)- Checking again: $2, 1, 9, 8, 1, 9, 8, 3, 7, 1, 9, 7, 8, 1, 2, 9, 1, 9, 8, 1, 8, 2, 1, 2$- The pattern $9, 1, 8$ appears once at the end of the sequence $(... 9, 1, 8 ...)$.- There are no other occurrences of $9, 1, 8$ or $8, 1, 9$ in the provided series.- Therefore,the correct answer is $1$.

In the following series of numbers,how many times have the figures $9, 1,$ and $8$ appeared together,with $1$ being in the middle and $9$ and $8$ being on either side of $1$ (i.e.,the sequence $9, 1, 8$ or $8, 1, 9$)?
$2, 1, 9, 8, 1, 9, 8, 3, 7, 1, 9, 7, 8, 1, 2, 9, 1, 9, 8, 1, 8, 2, 1, 2$
