Dang! I missed the Rosetta spec about spacing, that makes it much more tricky.

John from All BASIC has nice version.

Code: QB64: [Select]

1. _TITLE "Floyd John's version" ' from All BASIC 2018-10-17 looking pretty good!"
2. l = 14 'number of rows for Floyd to process
3. n = 1 ' number increment
4. FOR r = 1 TO l
5.     FOR c = 1 TO r
6.         PRINT RIGHT$("    " + STR$(n), LEN(STR$(c + l * (l - 1) / 2)));
7.         n = n + 1
8.     NEXT
9.     PRINT
10. NEXT
11.  

Notice how the spacing of columns is handled.
