Question

state convergent or divergent if convergent find the sum justify all answers mathematically

(n+1)/(2n+5) n=1 to infinity

Answer 1

use limit comparison test, with the DIVERGENT test series \[\frac{1}{n}\] or \[\frac{1}{2n}\]

Answer 2

Would you be able to explain in more detail please?

Answer 3

sorry, i misread the question.

you should use the divergence test, which states
in \[\sum a_n\] if \[\lim_{n\rightarrow \infty} a_n \neq 0\] then the series is divergent.

Answer 4

no worries, perfect then lol Thank you very much
