what is the ratio for the series 1/5, 1/8, 1/11, 1/14, 1/17.... i know that you add 3 to the denominator but what would the ratio be to see if it converges or diverges?

Question

There is no easy Un=kU(n-1) thing here.

anonymous · Answer

If expressed as a polynomial series, it'd have degree 4 at least. Do you want the series or the sum of the series to converge? The series tends to 0

anonymous · Answer

intuitively you would expect the sum of the  series to converge to a limiting value - thats as far as i can go im afraid

anonymous · Answer

hold on - the denominators are an arithmetical series  with  common difference of 3 -

anonymous · Answer

each term from 1/8 on can be written as 1 / ( 5 + 3n)  where n = 1,2,3....

anonymous · Answer

lol = -i  dont know if that helps!!

anonymous · Answer

does it converse or diverge?
