Refer to the following number and symbol series and answer the question that follows.
Counting to be done from left to right only.
(Left) ? > @ ^ @ \ ? + $ 6 7 \ 1 & @ 1 4 2 2 % 9 (Right)
How many such numbers are there, each of which is immediately preceded by a symbol and also immediately followed by another number?

The correct option is Two.

To find the total number of such numbers, we need to look for a pattern in the given series that satisfies the following rule:
Symbol ⇒ Number ⇒ Number

Let's analyze the given series from left to right:
(Left) ? > @ ^ @ \ ? + $ 6 7 \ 1 & @ 1 4 2 2 % 9 (Right)

Now, let's identify all the numbers that are immediately preceded by a symbol and immediately followed by another number:

1. In the sequence $ 6 7, the number 6 is immediately preceded by the symbol ($) and immediately followed by the number (7).

2. In the sequence @ 1 4, the number 1 is immediately preceded by the symbol (@) and immediately followed by the number (4).

No other numbers in the series satisfy both conditions simultaneously.

Therefore, there are exactly two such numbers (6 and 1).
