What will come in place of the questions mark (?) in the following number series ?
`56,232,944,?,15232`

Options

A. 4200
B. 3600
C. 3800
D. 3700

Answer

To find the missing number in the series `56, 232, 944, ?, 15232`, we can analyze the pattern of the series step by step.

### Step 1: Identify the pattern
The series appears to be increasing rapidly, suggesting a multiplication pattern followed by an addition.

### Step 2: Calculate the first transition
Starting with the first number:
- From **56** to **232**:
- We can see that \( 56 \times 4 = 224 \)
- Then, we add \( 8 \) to \( 224 \):
- \( 224 + 8 = 232 \)

### Step 3: Calculate the second transition
Next, we look at the transition from **232** to **944**:
- From **232** to **944**:
- We can see that \( 232 \times 4 = 928 \)
- Then, we add \( 16 \) to \( 928 \):
- \( 928 + 16 = 944 \)

### Step 4: Calculate the third transition
Now, we need to find the missing number that comes after **944**:
- From **944** to the next number (let's call it \( x \)):
- We can see that \( 944 \times 4 = 3776 \)
- The previous pattern shows that we added \( 8 \) then \( 16 \) (which is \( 8 \times 2 \)).
- Following this pattern, we can add \( 24 \) (which is \( 8 \times 3 \)):
- So, \( 3776 + 24 = 3800 \)

### Step 5: Calculate the final transition
Finally, we check the transition from **3800** to **15232**:
- From **3800** to **15232**:
- We can see that \( 3800 \times 4 = 15200 \)
- Then, we add \( 32 \) (which is \( 8 \times 4 \)):
- \( 15200 + 32 = 15232 \)

### Conclusion
Thus, the missing number in the series is **3800**.

### Final Answer
The number that comes in place of the question mark (?) is **3800**.
