Odd Give, Even Give Unequally...

It is interesting that,

\(\cfrac{\pi^2}{6}=\cfrac{1}{1^2}+\cfrac{1}{2^2}+\cfrac{1}{3^2}+...\)

and

\(\cfrac{\pi^2}{8}=\cfrac{1}{1^2}+\cfrac{1}{3^2}+\cfrac{1}{5^2}+\cfrac{1}{7^2}+...\)

but,

\(\cfrac{\pi^2}{24}=\cfrac{1}{2^2}+\cfrac{1}{4^2}+\cfrac{1}{6^2}+\cfrac{1}{8^2}+...\)

that odd and even numbers do not contribute equally to \(\sum^{\infty}_1{\cfrac{1}{n^2}}\)

\(\cfrac{3}{24}=\cfrac{1}{8}\ne\cfrac{1}{24}\)

Odd number contributes three times more than even numbers.

Why?
