What should come in place of the question mark (?) in the following number series ?
`"1520 760 380 190 95 47.5 ?"`

Options

A. 23.75
B. 22.25
C. 24.75
D. 21.25

Answer

To solve the number series: 1520, 760, 380, 190, 95, 47.5, ?, we need to identify the pattern in the series.

### Step-by-Step Solution:

1. **Identify the first term and the operation**:
- The first term is 1520.

2. **Divide the first term by 2**:
- \( 1520 \div 2 = 760 \)

3. **Divide the second term by 2**:
- \( 760 \div 2 = 380 \)

4. **Divide the third term by 2**:
- \( 380 \div 2 = 190 \)

5. **Divide the fourth term by 2**:
- \( 190 \div 2 = 95 \)

6. **Divide the fifth term by 2**:
- \( 95 \div 2 = 47.5 \)

7. **Divide the sixth term by 2**:
- \( 47.5 \div 2 = 23.75 \)

Thus, the value that should come in place of the question mark (?) is **23.75**.

### Final Answer:
23.75
