Scan for patterns of (Even Number тЖТ Symbol тЖТ Symbol) and count them sequentially from left to right.
Analyze the series
The given series is: 3, ╬й, 9, #, 1, 7, 3, @, 1, ^, 9, #, *, ┬г, 5, 8, $, 7, &, *, ┬г, 5. We need to find symbols preceded by an even number and followed by a symbol.
Identify potential even numbers
The even numbers in the series are 8. The only even number present in this series is 8. Let's look at 8: It is preceded by 5 and followed by $. This does not meet the condition (Even тЖТ Symbol тЖТ Symbol).
Verification of conditions
The condition is: Even Number тЖТ Symbol тЖТ Symbol. Let us check the symbols in the series: ╬й, #, @, ^, #, *, ┬г, $, &, *, ┬г. Checking the neighbors of these symbols, none of them are preceded by an even number (2, 4, 6, 8) and followed by another symbol.
B: 'One' is incorrect as no such triplet exists. C: 'More than two' is incorrect. D: 'Two' is incorrect.
A is correct because there is no symbol in the given series that is immediately preceded by an even number and immediately followed by a symbol.
When dealing with alphanumeric series, explicitly list out the positions of digits and symbols first to avoid missing a element during manual scanning.
