Ok. As you wish.
OpenStudy (iwanttogotostanford):
thank you
OpenStudy (3mar):
as it is geometric, and the numbers get bigger so the index is greater than one (which we multiply with)
OpenStudy (3mar):
Not at all!
OpenStudy (iwanttogotostanford):

Because there are positive and negative numbers in the sequence, so the base is negative (its negative sign diminishes in the case of even power)
Got that?
OpenStudy (iwanttogotostanford):

OpenStudy (3mar):
According to these givings, your choice is ...#?
OpenStudy (iwanttogotostanford):
