can you generate the next 4 rows?
at what point would the number of black overtake the number of red?

Are you sure that yours and curr3ent's images are identical?

Does your second question which row is mostly black, or at which row there are more cumulative blacks?

Looks like I have a square that is black where yours is red on the fourth row.

I had no idea what the tree was supposed to be. I was just extending patterns.

your right, should be black, not red. (should alternate black red black red)
for my second question, ignoring the outer most layer (my solution spoiler), which row is cumulative black more than cumulative red?

wait... in your triangle the "12th" diagonal has a square on 2,3,4,6,8 and 10 but not 9?

Another apparent oddity: the "diagonal" for 4 has a BLACK square for 4, 8, 12, 16, 20, but RED for 24
ALso, the "diagonal" for 9 has Black for 9, but Red for 18

Of course, these wouldn't be oddities if we understood the pattern...but I don't
