Odd One Out: Explanation
The given numbers are 331, 482, 551, 263, 383, 362, and 284. We need to identify the number that does not follow the given pattern.
Pattern:
- All the numbers are three-digit numbers except for 284.
- All the numbers have a unique combination of digits except for 263 and 551.
- All the numbers have a difference of 10 or more between their first and last digit except for 383 and 284.
Analysis:
- 331: It follows the pattern as it is a three-digit number, has a unique combination of digits, and the difference between its first and last digit is 2 (3-1).
- 482: It follows the pattern as it is a three-digit number, has a unique combination of digits, and the difference between its first and last digit is 2 (4-2).
- 551: It does not follow the pattern as it is a three-digit number, has a unique combination of digits, but the difference between its first and last digit is only 1 (5-5).
- 263: It does not follow the pattern as it is a three-digit number, has a repeating digit, and the difference between its first and last digit is only 3 (2-3).
- 383: It does not follow the pattern as it is a three-digit number, has a repeating digit, and the difference between its first and last digit is only 5 (3-8).
- 362: It follows the pattern as it is a three-digit number, has a unique combination of digits, and the difference between its first and last digit is 4 (3-6).
- 284: It does not follow the pattern as it is a three-digit number, has a repeating digit, and the difference between its first and last digit is only 4 (2-4).
Therefore, the odd one out is 383 as it is the only number that has a repeating digit and a difference of less than 10 between its first and last digit.

3×1=3, 4×2=8, 5×1=5, 2×3=6, [3×3=9], 3×2=6, 2×4=8
Therefore, option B is correct.
