so i am having trouble calculating the sum of the series of
(1+2^x)/(3^x) from 1 to infinity
i rearranged it and made a geometric series where r =2/3 and got that it converges toward 2. however the answer is 2.5? This problem shouldn't need any tests as its it a section of the book that hasant taught any of the tests, except for geometric so what am I doing wrong. I have been stuck on this for hours now? :(
