Scan the series strictly from left to right, looking for the specific triplet pattern: [Number] followed immediately by [Symbol], which is in turn followed immediately by another [Symbol].
Step 1: Understand the Condition
We need to find symbols that satisfy the exact pattern: Number followed immediately by Symbol, followed immediately by another Symbol (Number тЖТ Symbol тЖТ Symbol).
Step 2: Scan the Series from Left to Right
Given series:
Step 3: Identify Valid Triplets
Step 4: Final Count
There are exactly 3 such instances in the series. Therefore, the total count is 3.
A: 1 is incorrect as there are 3 valid occurrences. B: 4 is incorrect because careful left-to-right scanning reveals only 3 valid triplets. C: 2 is incorrect since counting all valid sequences yields 3.
D is correct because there are exactly 3 instances where a number is immediately preceded by nothing and followed by two consecutive symbols (5 + %, 4? $, and 3% @).
