I am wondering if it is possible to produce an input such as


for an arbitrary but fixed amount of n without having to type in every single term by hand. Note that the above is not supposed to be a list, but simply a sequence of variables and commas.

I thought that maybe a conversion of




could do the trick. Something similar was asked in the question How to replace plus sign by comma but it does not provide the solution I am after, since it produces a list instead of sequence. Is there a convenient way to get such an input sequence in Mathematica? Thanks for any suggestion!

    $\begingroup$ They're basically the same answer, but @MarcoB was first, so if he wants to post an answer, he can! $\endgroup$ – march Jul 16 '15 at 20:32

    $\begingroup$ This can actually be done without Sequence too: Fold[D, f[x, y, z], {x, y, z}]. $\endgroup$ – Szabolcs Jul 16 '15 at 20:46

    $\begingroup$ How about Array? Array[x, n] or Sequence@@Array[x,n] depending on what you are planning on doing with it. $\endgroup$ – bill s Jul 16 '15 at 23:32
