Pattern Analysis:

In this series, each number is obtained by adding a consecutive number to the previous number.

- The first number is 1.
- The second number is obtained by adding 2 to the previous number: 1 + 2 = 3.
- The third number is obtained by adding 3 to the previous number: 3 + 3 = 6.
- The fourth number is obtained by adding 4 to the previous number: 6 + 4 = 10.
- The fifth number is obtained by adding 5 to the previous number: 10 + 5 = 15.

The pattern can be summarized as follows:
1 + 2 = 3
3 + 3 = 6
6 + 4 = 10
10 + 5 = 15

So, the next number in the series would be obtained by adding 6 to the previous number:
15 + 6 = 21.

Answer:

The next number in the series is 21. However, none of the given options match this answer.
Therefore, the correct answer is "None of these".
