Symbol Series Analysis: Odd Preceded, Not Even Followed

Series Breakdown

The given number and symbol series is: $6 £ 2 @ % 7 8 # 1 3 * 9 $ & 4 ^ ≺ 5$

The task is to identify symbols that meet two conditions:

  • Condition 1: The symbol must be immediately preceded by an odd number.
  • Condition 2: The symbol must NOT be immediately followed by an even number.

Evaluating Symbols Against Conditions

We will check each symbol in the series:

  • £: Preceded by 6 (even). Fails Condition 1.
  • @: Preceded by 2 (even). Fails Condition 1.
  • %: Preceded by @ (symbol). Fails Condition 1.
  • #: Preceded by 8 (even). Fails Condition 1.
  • *: Preceded by 3 (odd). Meets Condition 1. Followed by 9 (odd). Meets Condition 2 (as 9 is not even). This symbol counts.
  • $: Preceded by 9 (odd). Meets Condition 1. Followed by & (symbol). Meets Condition 2 (as a symbol is not an even number). This symbol counts.
  • &: Preceded by $ (symbol). Fails Condition 1.
  • ^: Preceded by 4 (even). Fails Condition 1.
  • : Preceded by ^ (symbol). Fails Condition 1.

Final Count

The symbols meeting both criteria are * and $.

There are exactly Two such symbols.
