Look at the below pattern and complete the series:
11,15, 22, 26, 33, 37, 44, ?

Options

A. 45
B. 50
C. 55
D. 48

Answer

To solve the problem, we will analyze the given series step by step:

The series is: 11, 15, 22, 26, 33, 37, 44, ?

**Step 1: Identify the pattern in the series.**
- The series alternates between two sequences.
- The odd-positioned numbers are: 11, 22, 33, 44.
- The even-positioned numbers are: 15, 26, 37.

**Step 2: Analyze the odd-positioned numbers.**
- The odd-positioned numbers are: 11, 22, 33, 44.
- We can see that each number is increasing by 11.
- 22 - 11 = 11
- 33 - 22 = 11
- 44 - 33 = 11

**Step 3: Analyze the even-positioned numbers.**
- The even-positioned numbers are: 15, 26, 37.
- We can see that each number is also increasing by 11.
- 26 - 15 = 11
- 37 - 26 = 11

**Step 4: Determine the next number in the series.**
- The last number in the series is 44 (which is at an odd position).
- The next number in the series will also be at an even position, following the pattern of the even-positioned numbers.
- The last even-positioned number is 37.
- To find the next number, we add 11 to 37:
- 37 + 11 = 48.

**Final Answer:**
The next number in the series is **48**.
