SUMMARY
The series sum of 1/ln(n+5) from n=1 to infinity diverges. This conclusion is established using the comparison test, where it is shown that 1/ln(n+5) is greater than 1/n for n starting from 2. The divergence holds true even when the comparison starts at n=2, as the behavior of the series from n=1 does not affect the overall divergence. Therefore, the proof remains valid despite the initial index of summation.
