Refer to the following number, symbol series and answer the question. Counting to be done from left to right only.

(Left) 2 6 # @ 8 $ 7 + 1 * £ 5 & 3 Ω 9 % 4 (Right)

How many such symbols are there each of which is immediately preceded by a number and also immediately followed by another number?

Given series: (Left) 2 6 # @ 8 $ 7 + 1 * £ 5 & 3 Ω 9 % 4 (Right)

According to the question such symbols are there which are immediately preceded by a number and also immediately followed by another number:

Required condition: Number - Symbol - Another number

(Left) 2 6 # @ 8 $ 7 + 1 * £ 5 & 3 Ω 9 % 4 (Right)

Thus, there are five such symbols are there which are immediately preceded by a number and also immediately followed by another number.
