Question 1148527
<pre>
It's not (A), for that would be  {{{1/1}}}{{{1/2 }}}{{{1/3 }}}{{{1/4,}}}{{{ 1/5 }}}... {{{1/(n)...}}}

It's not (B), for that would be  {{{1/3 }}}{{{1/4 }}}{{{1/5,}}}{{{ 1/6 }}}... {{{1/(n+2)}}}...

It's not (C), for that would be a "two-way" sequence that goes "left and right":

...{{{1/(n+1)}}}{{{1/(-5)}}}{{{1/(-4)}}}{{{1/(-3)}}}{{{1/(-2)}}}{{{1/(-1)}}} {{{1/0}}}{{{1/1}}}{{{1/2}}}{{{1/3}}}{{{1/4}}}{{{1/5}}}...{{{1/(n+1)...}}}

but that contains the undefined term "1/0". So that's not it. 

If the following were listed I would pick this:

{{{matrix(1,7,1/(n+1), "",n,is,all,positive, integers)}}}

I would hesitate to pick (D) for it says nothing about n being and integer.

But I would also hesitate to pick (E)  

However, after thinking about it, I would pick (D) after all because you are
given that it is an infinite sequence, so it would not be necessary to say that
n is an integer.
