Question? :)

OpenStudy (anonymous):

How can I work out this geometric sequence -4 , 12 , 36

OpenStudy (anonymous):

Now you have to find a_4 , a_5 and so on :) Also remember the formula I gave above only applies only if r>1

OpenStudy (anonymous):

I am sorry I gave you sum of Gp formula earlier. The corect formula is a_n = a*r^(n-1) r = common ratio = 2nd term / 1st term
