What are the next two terms in the sequence?

You should be able to solve this
>>
Well, I thought it was just a 1D CA at first, but there's a BWB trio in line 8 that produces a black.
>>
OP here
I've generated this sequence to ~30 terms
I can give you more lines if you think it will help you find the pattern
But hints are for sissies

>>7734401 again.

Think I got it now. Took me a second to notice that "prime" rows were blank in the middle, but that did it.

Line 13 is correct but line 14 is wrong

>>7734421
you got both wrong

I think you've earned a hint
>>
>>7734421

Exactly what I got, but I will admit I don't know much about math and came both to this board out of curiosity and to the pictured conclusion solely based on physical pattern
>>
>>7734421
OP again; whoops, you actually got 14 right

Now I'm confused; how did you get your answer?
>>
>>7734435
I followed the pattern in each column, then noticed that 13 isnt symmetrical like the rest. So I checked all the diagonals and noticed another pattern, so I added that one more in row 13.
>>
>>7734435
Thought so.

View the squares going from left to right as 0, 1, ..., k for the kth row.

Fill 0, don't fill 1, and for all others, fill in the jth square if j divides k.
>>
>>7734441
Whoops, thought you were responding to >>7734412. Apparently something else is wrong with what I'm doing.
>>
>>7734441
>>7734446
Look at row 8. 4 and 6 don't divide 8, so j doesn't always divide k.
>>
>>7734441
And I even fucked up the explanation of what I did. Fill 0, don't fill 1, and for all others, fill in the jth square if j shares a divisor bigger than 1 with k.

You're a smart dude. You get the Smart Motherfucker medal
>>
>>7734387
Easy. Label the columns 0, 1, 2, ... from right to left. The cell in row x and column y is white if [math]\gcd(x,y)=1[/math], and black otherwise.
>>
>>7734412
The only thing I don't understand with yours is why you aimed the middle square was filed in the 14th row, while the diagonal pattern indicate it should be empty.
>>
>>7734536
gcd(7,14)=7>1.

>>7734471
>>7734542
But this breaks down in that row, since OP stated that the anon who said the middle block of 14 was white was correct. (>>7734435 )
>>
>>7734559
I think he quoted the wrong guy in that post, considering that he said >>7734451 is right.

this?

woah

>>7734555
Trips don't lie.
>>
>>7734643
no, in 13 you have the first block filled in and the last one filled in. in 14, you have every other one filled in, so you're missing one block in column 7.
