It is always hard to define a 'closed form expression' but you may have an idea for the meaning of closed form that is intended here. Take for example the simple sum, $$\displaystyle \sum_{k=1}^n k=\dfrac{n(n+1)}{2}$$ The R.H.S formula is the 'closed form' for the sum. Also notice that for my work the explicit expression for the sum isn't needed, only remarks on parity of the sum is needed. | |
