Find the wrong number in the following number series questions.
16000,8000,24000,6000,30000,7500,35000

Options

A. 8000
B. 7500
C. 30000
D. 60000

Answer

To find the wrong number in the series: 16000, 8000, 24000, 6000, 30000, 7500, 35000, we will analyze the pattern of the series step by step.

### Step 1: Identify the Pattern
First, we will look for a pattern in the series. We can see that the series alternates between dividing and multiplying.

1. **16000 to 8000**:
- Here, we divide 16000 by 2.
- Calculation: \( 16000 \div 2 = 8000 \)

2. **8000 to 24000**:
- Now, we multiply 8000 by 3.
- Calculation: \( 8000 \times 3 = 24000 \)

3. **24000 to 6000**:
- Next, we divide 24000 by 4.
- Calculation: \( 24000 \div 4 = 6000 \)

4. **6000 to 30000**:
- Then, we multiply 6000 by 5.
- Calculation: \( 6000 \times 5 = 30000 \)

5. **30000 to 7500**:
- Now, we divide 30000 by 6.
- Calculation: \( 30000 \div 6 = 5000 \)

6. **7500 to 35000**:
- Finally, we multiply 5000 by 7.
- Calculation: \( 5000 \times 7 = 35000 \)

### Step 2: Identify the Wrong Number
From the calculations, we see that when we divide 30000 by 6, we should get 5000, but the series shows 7500 instead.

Thus, the wrong number in the series is **7500**.

### Final Answer
The wrong number in the series is **7500**; it should be **5000**.
