Odd One Out — Among 339, 428, 338, and 326, select the number that differs in parity relative to the others.

Introduction / Context:
Parity (odd vs even) is a common, simple discriminator in number-classification tasks.

Given Data / Assumptions:

• Numbers: 339, 428, 338, 326.
• Even numbers are divisible by 2; odd numbers are not.

Concept / Approach:
Check divisibility by 2 for each option.

Step-by-Step Solution:
428: even.338: even.326: even.339: odd.Only one value is odd, so it is the outlier.

Verification / Alternative check:
Last-digit check: even numbers end in 0,2,4,6,8; 339 ends in 9.

Why Other Options Are Wrong:

• 428: even, matches the majority set.
• 338: even, matches the majority set.
• 326: even, matches the majority set.

Common Pitfalls:
Overcomplicating the pattern; here the simplest parity rule solves it.

Final Answer:
339
