so unnecessary to spam...
first define the geometric sequence.
its the bottoms they all mutiply by themselves
not just 4, by negative 4 since it changes sign, correct?
see thats where I get confused
So you start with 1. You multiply by (-1/4) you get (-1/4)
then you multiply again my -1/4
so you get (1/16) since the negative multiplied by negative is a positive, correct?
So that, is what we call the "r" term in a geometric series (ie. the number we always multiply with)
do you know the sum of a geometric sequence, the formula?
so to find the sum? how do I use that with the figures
do u mean like s with the little n
hmm... actually since your question is asking how to find the sum of the ***finite*** geometric series, you could probably add them all together
so Id get 7/ over and bottom total added?
Try again, in order to add fractions they need a common denominator...
7/ 4096...OR DO YOU MEAN LIKE 28/4096
... it's actually 3277/4096
oh...wow I like the page I will have to check that out.. thanks
you could have also used the S n thing as well to figure it out. Probably easier.
