Scan the series for the specific triplet pattern [Number] [Symbol] [Number] by focusing on adjacent digits surrounding a symbol.
Identify the Condition
We need to find symbols that have a number immediately on their left and a number immediately on their right (Number - Symbol - Number).
Scan and Test Each Symbol
Checking the series 4 @ ^ 8 2 # 7% 3 * 9 < 5 $6 @ * 1, we find four qualifying segments: 2 # 7 (#), 7% 3 (%), 3 * 9 (*), and 9 < 5 (<).
Count the Valid Symbols
Counting these valid occurrences gives a total of 4 matching symbols, which corresponds to Option C.
A: 3 is incorrect because it misses one of the valid occurrences. B: 2 is incorrect because it severely underestimates the matched pairs. D: 1 is incorrect as it only counts a single symbol.
C is correct because there are exactly 4 symbols that satisfy the condition of being immediately preceded and followed by a number.
Mark the positions of numbers and symbols separately during your scan to prevent overlooking nested or consecutive patterns.
