What does that even mean??

I can't follow your derivative argument at all, but you did (accidentally?) come up with the following:
> (1+2+3+4+5) is a triangular sum
And the formula for that sum is [math]T_n = \dfrac{n(n+1)}{2}[/math]. In your argument [math]n = x - 1[/math], so
[eqn]2 T_{x-1} + x = 2 \dfrac{(x-1)(x - 1 +1)}{2} + x = x(x-1) + x = x^2[/eqn]

I have no idea how you are expecting to calculating a series sum without knowing how long it is (x).

Yep, it was bait.

Looks like it is true lmao.
