Interestingly,
- The sequence (-1)^n(n^(1/n)-1) is not “open” in the sense that it
doesn’t diverge or expand indefinitely. Instead, it oscillates
.
- It is not “closed” either for individual terms, because they do not
settle into a single value or a finite set of values.
Instead, we focus on the convergence of the series formed by these terms, which leads to the MRB constant.
