The missing number in the given series is 21.
Explanation:
Pattern in the series:
To find the missing number in the series, we need to identify the pattern followed by the given numbers.
Looking at the given series, we can observe the following pattern:
1st number: 3, 6, 9, 57 (increasing by 3)
2nd number: 4, 7, 1, 11 (increasing by 3, but wrapping around from 9 to 1)
3rd number: 5, 8, 2, ? (increasing by 3, but wrapping around from 9 to 2)
Applying the pattern:
Now, let's apply the identified pattern to find the missing number in the series.
1st number: 3, 6, 9, 57 (increasing by 3)
2nd number: 4, 7, 1, 11 (increasing by 3, but wrapping around from 9 to 1)
3rd number: 5, 8, 2, ? (increasing by 3, but wrapping around from 9 to 2)
Following the pattern, the missing number in the 3rd position should be 2 + 3 = 5.
Therefore, the missing number in the series is 21.
Conclusion:
The missing number in the given series is 21, which matches with option B.

Step 1: Apply the rule for each column
Column 1:
- Numbers: 3, 6, 9
- Formula: Multiply the last two numbers and add the first number.
- 6 × 9 = 54 and 3 + 54 = 57
- The first number in the last row is 57, so this is correct.
Column 2:
- Numbers: 4, 7, 1
- Formula: Multiply the last two numbers and add the first number.
- 7 × 1=7 and 4 + 7 = 11
- The second number in the last row is 11, so this is correct.
Column 3:
- Numbers: 5, 8, 2
- Formula: Multiply the last two numbers and add the first number.
- 8 × 2 = 16 and 5+16 = 21
- So the missing number in the last row is 21.
Final Answer:
The missing number is 21.
