Look for a triplet in the format: (Number, Number, Symbol). Scan the series for sequences where two digits appear consecutively, followed by any non-digit symbol.
Look for a triplet in the format: (Number, Number, Symbol). Scan the series for sequences where two digits appear consecutively, followed by any non-digit symbol.
Analyze the condition
We are looking for a triplet: [Number] - [Number] - [Symbol]. This means we need two consecutive numbers where the second number is immediately followed by a symbol.
Scan the series
Series: 2, %, 8, 4, 5, 3, @, #, 1, *, $, 7, &, 9, +, ╬й, 6, ┬г. Consecutive numbers: (8,4), (4,5), (5,3). Checking the symbols following these: (8,4) is followed by 5 (not a symbol), (4,5) is followed by 3 (not a symbol), (5,3) is followed by @ (a symbol).
Verify triplet (5, 3, @)
In the triplet (5, 3, @): 3 is the 'number' we are checking. Is it preceded by a number? Yes (5). Is it followed by a symbol? Yes (@). This satisfies the condition. Checking further: are there any others? No other consecutive numbers are followed by a symbol.
A: 0 is incorrect because 1 such number exists. B: 1 is correct. C: 2 is incorrect. D: None/Other is incorrect as 1 is the identified count.
B is correct because the number 3 is immediately preceded by the number 5 and immediately followed by the symbol @, forming exactly one such valid instance.
Always break down complex conditions into distinct attributes (Preceded by X, Followed by Y) and verify the sequence step-by-step to avoid missing elements.
