Homework Statement
I have to say if the series converge or diverge.
[tex]\infty[/tex]
[tex]\sum[/tex] LN(n[tex]/2n+5[/tex])
n=1
Homework Equations
I found this series to be divergent. However, I don't know if the way I proceeded is correct.
The Attempt at a Solution
I first separated the ln into two lns ( ln(n) - ln(2n+5 ). Then, I used it as a power of e to remove the lns, thus being left with -n -5. I then went for the limit divergence test, and it ended up diverging.
Do I have the right to proceed that way?
