What will come in place of question mark (?) in the given question
44 41 36 29 18 ?

Options

A. 5
B. 11
C. 3
D. 7

Answer

To find the missing number in the sequence 44, 41, 36, 29, 18, ?, we will analyze the differences between the consecutive numbers.

1. **Step 1: Identify the differences between consecutive terms.**
- 44 to 41: 44 - 41 = 3
- 41 to 36: 41 - 36 = 5
- 36 to 29: 36 - 29 = 7
- 29 to 18: 29 - 18 = 11

So, the differences are: 3, 5, 7, 11.

**Hint:** Look for a pattern in the differences between the numbers.

2. **Step 2: Recognize the pattern in the differences.**
- The differences are 3, 5, 7, and 11. These numbers are all prime numbers.
- The sequence of prime numbers starts with 2, 3, 5, 7, 11, and the next prime number after 11 is 13.

**Hint:** Identify if the differences follow a specific sequence or pattern.

3. **Step 3: Calculate the next difference.**
- Since the last difference we used was 11, the next difference should be 13 (the next prime number).

**Hint:** Determine the next number in the series of prime numbers.

4. **Step 4: Subtract the next difference from the last number in the sequence.**
- Now, we will subtract 13 from the last number in the sequence, which is 18.
- 18 - 13 = 5.

**Hint:** Perform the subtraction to find the missing number.

5. **Step 5: Conclusion.**
- The missing number that replaces the question mark (?) is 5.

Thus, the final answer is 5.

**Final Answer:** 5
