Refer to the following number and symbol series and answer the question that follows. Counting to be done from left to right only. All numbers are single-digit numbers only.

(Left) © 3 @ 8 5 1 £ 1 6 1 5 7 2 8 # € £ © € © 1 3 (Right)

How many such numbers are there each of which is immediately preceded by a symbol and also immediately followed by a symbol?4256

The correct answer is Option 1 (which is 1).

To find the total count of such numbers, let us analyze the given series from left to right based on the specified condition.

Required Condition:
We need to find numbers that satisfy the pattern:
Symbol → Number → Symbol

Let us examine the given sequence step by step:

(Left) © 3 @ 8 5 1 £ 1 6 1 5 7 2 8 # € £ © € © 1 3 (Right)

Let us check all the numbers in the series:

1. 3: Preceded by '©' (symbol), followed by '@' (symbol). (Matches the pattern: © 3 @)
2. 8: Preceded by '@' (symbol), followed by '5' (number). (Does not match)
3. 5: Preceded by '8' (number), followed by '1' (number). (Does not match)
4. 1: Preceded by '5' (number), followed by '£' (symbol). (Does not match)
5. 1: Preceded by '£' (symbol), followed by '6' (number). (Does not match)
6. 6: Preceded by '1' (number), followed by '1' (number). (Does not match)
7. 1: Preceded by '6' (number), followed by '5' (number). (Does not match)
8. 5: Preceded by '1' (number), followed by '7' (number). (Does not match)
9. 7: Preceded by '5' (number), followed by '2' (number). (Does not match)
10. 2: Preceded by '7' (number), followed by '8' (number). (Does not match)
11. 8: Preceded by '2' (number), followed by '#' (symbol). (Does not match)
12. 1: Preceded by '©' (symbol), followed by '3' (number). (Does not match)
13. 3: Preceded by '1' (number), at the end of the series. (Does not match)

Thus, there is only 1 such number (which is 3 in the group © 3 @) that is immediately preceded by a symbol and also immediately followed by a symbol.
