What follows next after 1-3-6-10-15-20?
The sequence given is formed by the triangular numbers, which are obtained by adding consecutive integers. The next number in the sequence after 20 can be calculated by adding 6 (the next integer after 5, which was added to get 15 to 20). Therefore, the next number is 20 + 6 = 26. So, the next number is 26.
