+865 In the geometric sequence with a first term of 6 and a second term of -6, what is the 205^th term?
+37155 COmmon ratio r 1st term 6 multiplied by common ratio yields second term
so r = -1
this sequence just bounces back and forth between 6 and -6
even numbered terms are negative (like the second term above)
odd numbered terms are positive
205 th term would be +6
