Options

A. A)7200
B. B)1800
C. C)6000
D. D)2250

Answer

To find the wrong term in the given number series: 7200, 1200, 6000, 1800, 4500, 2250, 2250, we will analyze the pattern of the series step by step.

### Step-by-Step Solution:

1. **Identify the Terms**:
The series is:
- 1st term: 7200
- 2nd term: 1200
- 3rd term: 6000
- 4th term: 1800
- 5th term: 4500
- 6th term: 2250
- 7th term: 2250

2. **Check the Pattern**:
We will look for a pattern in the series. The pattern appears to alternate between division and multiplication.

3. **First Operation**:
- From the 1st term to the 2nd term:
\[ 7200 \div 6 = 1200 \]
This is correct.

4. **Second Operation**:
- From the 2nd term to the 3rd term:
\[ 1200 \times 5 = 6000 \]
This is also correct.

5. **Third Operation**:
- From the 3rd term to the 4th term:
\[ 6000 \div 6 = 1000 \]
However, the 4th term given is 1800, which is incorrect. The correct term should be 1000.

6. **Fourth Operation**:
- If we had the correct 4th term (1000), then from the 4th term to the 5th term:
\[ 1000 \times 4 = 4000 \]
But the 5th term given is 4500, which is also incorrect.

7. **Fifth Operation**:
- Continuing with the correct 5th term (4000):
\[ 4000 \div 5 = 800 \]
But the 6th term given is 2250, which is incorrect.

8. **Conclusion**:
The pattern is not consistent after the 4th term. The 4th term (1800) is the first incorrect term. The correct term should be 1000.

### Final Answer:
The wrong term in the series is **1800**.
