What will come in place of question mark (?) in the following series?
4,9,16,25,?

Options

A. 49
B. 30
C. 36
D. 42

Answer

To solve the given number series: 4, 9, 16, 25, ?, we will identify the pattern in the series step by step.

### Step 1: Identify the numbers in the series
The numbers provided in the series are:
- 4
- 9
- 16
- 25

### Step 2: Recognize the pattern
We can observe that each number in the series is a perfect square:
- 4 is \(2^2\)
- 9 is \(3^2\)
- 16 is \(4^2\)
- 25 is \(5^2\)

### Step 3: Continue the pattern
Following the pattern of perfect squares, the next number should be the square of the next integer:
- The next integer after 5 is 6.
- Therefore, the next number in the series will be \(6^2\).

### Step 4: Calculate \(6^2\)
Calculating \(6^2\):
\[ 6^2 = 36 \]

### Conclusion
Thus, the number that will come in place of the question mark (?) in the series is **36**.

### Final Answer
The answer is **36**.
