#Recurrence and Closed Form

does "closed form" mean "general form"?
@honest sundial Have you heard of generating functions?
It doesn't say you're not supposed to.
Then I have no clue how you're supposed to find the explicit formula.
I mean, that's how I found it.
Yeah, I'm looking at it.
...anyway, if you have the explicit formula, then... what do you need help with?
Me neither, frankly.
Like I said, I just used a generating function.
Okay, well, I do note that lines 1 and 2 are just rearrangements of the recursive formula.
Then Line 3 is Line 1 times 2, and Line 4 is Line 2 times 4.
...because... look at them?
I don't know.
