Question 846929
<pre>
Yes, you are correct, but that last term of the sequence
{{{0.5/729}}} should be simplified so that the numerator
will be an integer. 0.5 needs to be multiplied by 2 to
get the integer 1.  So multiply the term by {{{2/2}}}

{{{0.5/729}}}{{{"×"}}}{{{2/2}}}{{{""=""}}}{{{1/1458)}}}

Written that way, you can't see how it fits the pattern 
anymore, but it does, and is the correct 7th term.
