Given Sequence: 3, 5, 11, 14, 17, 21
To find the missing number from the given options, we need to analyze the pattern followed in the sequence.
Observations:
- The difference between the first and second numbers is 5 - 3 = 2.
- The difference between the second and third numbers is 11 - 5 = 6.
- The difference between the third and fourth numbers is 14 - 11 = 3.
- The difference between the fourth and fifth numbers is 17 - 14 = 3.
- The difference between the fifth and sixth numbers is 21 - 17 = 4.
Pattern:
- The differences between the numbers are not constant.
- However, the differences alternate between 3 and 4.

- To find the missing number, we need to determine the difference between the fifth and sixth numbers.
- Since the difference between the fifth and sixth numbers is 4, the missing number should be 17 + 4 = 21.
Conclusion:
The missing number from the given options is 21. Therefore, the correct answer is C: 21.
