331,482,551, 263,383,242,111

Options

A. 263
B. 383
C. 242
D. 111

Answer

To find the odd term in the series: 331, 482, 551, 263, 383, 242, 111, we will analyze each term based on a specific pattern.

### Step-by-Step Solution:

1. **Identify the Structure of Each Term**:
Each term in the series can be broken down into three digits. For example:
- 331 → 3, 3, 1
- 482 → 4, 8, 2
- 551 → 5, 5, 1
- 263 → 2, 6, 3
- 383 → 3, 8, 3
- 242 → 2, 4, 2
- 111 → 1, 1, 1

2. **Apply the Pattern**:
We will check if the second digit of each term is equal to the product of the first and third digits.
- For 331: \(3 \times 1 = 3\) (Matches the second digit 3)
- For 482: \(4 \times 2 = 8\) (Matches the second digit 8)
- For 551: \(5 \times 1 = 5\) (Matches the second digit 5)
- For 263: \(2 \times 3 = 6\) (Matches the second digit 6)
- For 383: \(3 \times 3 = 9\) (Does NOT match the second digit 8)
- For 242: \(2 \times 2 = 4\) (Matches the second digit 4)
- For 111: \(1 \times 1 = 1\) (Matches the second digit 1)

3. **Identify the Odd Term**:
From the above checks, we see that all terms follow the pattern except for 383, where \(3 \times 3 = 9\) does not equal the second digit 8.

Thus, the odd term in the series is **383**.
