What are the next numbers in the sequence and why?

1, 1, 1, 2, 1, 3, 1, 4, 6, 1, 5, 10, 1, 6, 15, 20, 1, 7, .. , .. , ..

Please try to avoid searching the internet for this

21,35,1

These would be the left half of Pascal's Triangle.

1
1,1
1,2,1
1,3,3,1
1,4,6,4,1
1,5,10,10,5,1
1,6,15,20,15,6,1
1,7,21,35,35,21,7,1
1,8,28,56,70,56,28,8,1

the last number shown is 7 and only the left half is used, so ..... that would be 21 and 35 followed by the starting 1 of the 9th row.
