In a geometric progression,the 6th term is 96 and the common ratio is -2. Find the sum of the first 6 terms of the progression.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

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%2F2.
The sum of its 6 terms is the same as the sum of the six terms of the original progression.
