do you need to know the formula?
It's just adding 1 using binary numbers.
But the problem with puzzles like this is that there is no one answer.
Like I could have said that A(n) = [A(n-1)*A(n-2)] + (-1)^n*[A(n-2)]
Meaning multiply the previous 2 terms and alternate adding and subtracting the 2nd ago term. (where A(0) = 1 and A(1) = 10)
And then the next 3 numbers would be 1111, 111000, 123322111
