That is farther! You need to go down.
>give me a hint
I don't know how to! I don't really know how you got the answers you already did so I'm afraid of accidentally revealing too much. How did you get b)? Normally the way I solved it, it's almost identical to a) so if you got one, you get the other too unless you make a calculation error. Divisors of 4 are 4,2 and 1. I'll say that.

Good luck anon! I believe in you! We'll get the correct answer very soon!

Good job anon. Your answer is correct! Your solution is quite similar to how the book does it minus the picture and instead with more typing.
Thank you for your time and effort solving this. I appreciate it!

Great job anon! Your answer is also correct!
Quite a unique way of going about it too. The recursive formula you found almost looks like Pascal's identity to me. All around very cool.
Thank you a lot for your time and effort solving this.

I personally went with counting way to find the closed form. That also gets the answer without much symbol writing.

Thank you both again for doing this.I hope it was fun for you. And actually, if you don't mind, tell me if you actually found this fun or not. And if it was a nice problem/exercise to tackle.
