comment How Can I Reform This Sequence?
This is not an answer. You make this sound like a riddle where your friend purposefully withholds information, so I ask you whether you have a reason to believe that a function exists. There are plenty of reasons why not. If you just write an arbitrary expression like the above, it just won't have a simple closed form in one variable.

Do you have a reason to believe that a simple one-variable function exists?

comment How does learning math affect other skills?
I am annoyed by your question. Could that mean that choosing user names starting with A makes people more annoying? I suggest that you learn about gender role history before you claim that "women have traditionally be deemed more fluid with words" and that this is supported by Psychology. It might also be somewhat relevant that the placebe control group of men thinking they got an estrogen contraception pill complained about the "side effects" of being more emotional, etc.

comment A Case Against the “Math Gene”
If the ability to do math were determined at birth, then no math education would be necessary. This critique is not mere quibbling over formulation, the ill-posed question is at the heart of the problem of "nature versus nurture". I have answered the implied question on the problem of attitude of teachers and students below.

You can just stereo-look at the two drawings and the differences will jump out into the third dimension.

This is a proof for the irrationality that you are seeking.

comment Recursion with non-equal exponents
What kind of functions on which domain are you looking for? Do you have an example? Are the functions continuous? Or functions on the natural numbers ? Are there initial conditions?`Are you looking for asymptotics?
