What will come in place of question mark (?) in the following sereis questions?
5,15,75,525,4725,?

Options

A. A)52052
B. B)54450
C. C)48840
D. D)51975

Answer

To solve the series: 5, 15, 75, 525, 4725, ?, we need to identify the pattern in the sequence.

### Step-by-Step Solution:

1. **Identify the Pattern:**
- Look at the relationship between consecutive terms.
- From 5 to 15: \(5 \times 3 = 15\)
- From 15 to 75: \(15 \times 5 = 75\)
- From 75 to 525: \(75 \times 7 = 525\)
- From 525 to 4725: \(525 \times 9 = 4725\)

2. **Recognize the Multipliers:**
- The multipliers are: 3, 5, 7, and 9.
- Notice that these multipliers are increasing by 2 each time (3, 5, 7, 9).

3. **Determine the Next Multiplier:**
- Following the pattern, the next multiplier should be \(9 + 2 = 11\).

4. **Calculate the Missing Term:**
- Now, multiply the last known term (4725) by the next multiplier (11):
\[ 4725 \times 11 = 51975 \]

5. **Conclusion:**
- Therefore, the missing term in the series is **51975**.

### Final Answer:
The value that will come in place of the question mark (?) is **51975**.
