~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
The reversed progression (6-th term, 5-th term, 4-th term and so on) is geometric progression with the first term 96 and the common ratio of {{{-1/2}}}.
The sum of its 6 terms is the same as the sum of the six terms of the original progression.

Is it enough for you to complete calculations?
