Scan the series for numbers and check their immediate left and right neighbors to see if both are symbols.
Step 1: Understand the Condition
We need to find numbers in the given series that are immediately preceded by a symbol AND immediately followed by a symbol (Symbol тЖТ Number тЖТ Symbol).
Step 2: Examine All Numbers in the Series
Given series: 7, 8, &, $, &, 2, @, %, 4, 6, 3, ╬й, ┬г, 5, 1, 9, #, *
Step 3: Count the Valid Numbers
Only one number (2) satisfies the given condition. Therefore, the total count is One.
B: 'More than two' is incorrect because only one valid number exists. C: 'Two' is incorrect as there is only one match. D: 'Zero' is incorrect because number 2 meets the condition.
A is correct because exactly one number (2) is immediately preceded by a symbol (&) and followed by a symbol (@).
In similar series questions, always list each target element first, then inspect its immediate left and right neighbors simultaneously to avoid counting errors.
