Find the wrong term in following number series
84,96,83,95,80,94,81

Options

A. 95
B. 81
C. 83
D. 80

Answer

To find the wrong term in the series 84, 96, 83, 95, 80, 94, 81, we can analyze the pattern of the numbers step by step.

### Step-by-Step Solution:

1. **Identify the Pattern**:
- The series appears to alternate between two sequences. Let's separate the even and odd indexed terms:
- Odd indexed terms: 84, 83, 80, 81
- Even indexed terms: 96, 95, 94

2. **Analyze the Odd Indexed Terms**:
- The odd indexed terms are: 84, 83, 80, 81
- Here, we can see:
- 84 to 83: Decrease by 1
- 83 to 80: Decrease by 3
- 80 to 81: Increase by 1
- The expected pattern seems to be a decrease by 1, then a decrease by 1 again (not a decrease by 3).

3. **Analyze the Even Indexed Terms**:
- The even indexed terms are: 96, 95, 94
- Here, we can see:
- 96 to 95: Decrease by 1
- 95 to 94: Decrease by 1
- This pattern is consistent.

4. **Identify the Anomaly**:
- In the odd indexed terms, the transition from 83 to 80 is a decrease of 3, which disrupts the expected pattern of decreasing by 1.
- If we follow the pattern, after 83, we should have 82 (not 80).

5. **Conclusion**:
- The wrong term in the series is **80**. It should have been **82** to maintain the pattern.

### Final Answer:
The wrong term in the series is **80**.
