Answer 2

The sequence you provided appears to be an arithmetic progression where each number increases by a constant difference. Let's analyze it:

1, 3, 6, 10, 15, ?

The difference between each consecutive pair of numbers is as follows:

3 - 1 = 2 6 - 3 = 3 10 - 6 = 4 15 - 10 = 5

As you can see, the difference between each pair of consecutive numbers is increasing by 1 each time. So, to find the next number in the sequence, you can continue this pattern:

15 + 6 = 21

So, the next number in the sequence should be 21. Therefore, the correct answer is B) 21.
