What will come in place of question mark (?) in the given number series?
9 4 3 3 4 ?

Options

A. 11
B. 7.5
C. 9.5
D. 12

Answer

To solve the number series: 9, 4, 3, 3, 4, ?, we need to identify the pattern in the series.

### Step 1: Analyze the series
The given series is: 9, 4, 3, 3, 4, ?

### Step 2: Find the relationship between the numbers
1. From 9 to 4:
- We can see that 9 is reduced to 4.
- The operation can be represented as:
\[ 9 \times 0.5 = 4.5 \quad \text{(then subtract 0.5)} \]
- So, \( 9 - 0.5 = 4 \).

2. From 4 to 3:
- Here, we can see that:
\[ 4 \times 1 = 4 \quad \text{(then subtract 1)} \]
- So, \( 4 - 1 = 3 \).

3. From 3 to 3:
- Here, we can see that:
\[ 3 \times 1.5 = 4.5 \quad \text{(then subtract 1.5)} \]
- So, \( 3 - 1.5 = 3 \).

4. From 3 to 4:
- Here, we can see that:
\[ 3 \times 2 = 6 \quad \text{(then subtract 2)} \]
- So, \( 3 - 2 = 4 \).

### Step 3: Predict the next number
Now, we need to find the next number after 4:
- We will multiply 4 by 2.5:
\[ 4 \times 2.5 = 10 \quad \text{(then subtract 2.5)} \]
- So, \( 10 - 2.5 = 7.5 \).

### Conclusion
Thus, the number that will come in place of the question mark (?) is **7.5**.
