a convergent geometric sequence with
first term a is such that the sum of
the terms after the n^(th) term is
three times the n^(th) term, find the
common ratio and show that its
sum to infinity is 4a.
Posting Question with Images
Preferably you should type the question.
However if you are using pictures then
please do the following steps
which posting a photo of printed
question.
A. Use camscanner app to take
pictures (search for camscanner in
playstore).
B. Crop picture so that you only
have specifc question that you want
to ask in the image.
(3+((cq)/(12b)))s^2 +((6c)/b)s+(((8c^2 )/(3b^2 ))−b)=0
(1+((cq)/(4b)))s^2 +((3c)/b)(1−((cq)/(12b)))s+(((12c^2 )/b^2 )−b)=0
solve simultaneously for q and s
in terms of b and c.
