Look for a digit that has both a left and right neighbor that are also digits. Scan the series quickly for consecutive digit triplets like '123'.
Identify Target Condition
The question requires identifying numbers that are immediately preceded by a number AND followed by a number. This means looking for a sequence of 3 consecutive numbers (Number-Number-Number).
Scan the Sequence
The series is: 5, #, *, 7, 9, %, 2, &, 1, >, 6, @, 3, ^, 4, , >, 8. \text{Breaking it down}: 5 (next is #), 7 (next is 9, \text{prev is} *), 9 (next is \%, prev is 7), 2 (next is &, prev is \%), 1 (next is >, prev is &), 6 (next is @, prev is >), 3 (next is ^, prev is @), 4 (next is , prev is ^), 8 (prev is >).
Verification
At no point in the series are there two or more numbers adjacent to each other. Every number is separated by either symbols or non-numeric characters. Thus, the count of numbers satisfying the condition is zero.
B: Incorrect, as there are no instances of three consecutive digits. C: Incorrect, as the count is zero, not two. D: Incorrect, as the count is zero, not three.
A is correct because the series contains no consecutive three-digit patterns (Number-Number-Number) required by the condition.
In symbol-series questions, always categorize elements (Number, Symbol, Alphabet) first to simplify the visual scan.
