Question

I'm trying to figure out how to reindex a series into another one. (Math posted in a moment.)

Answer 1

Original series:

\[\sum_{n = 1}^{\infty} (\frac{ n }{ 2n+3 })^{n}\]

Answer 2

I need to reindex that into...\[\sum_{n = ?}^{\infty}(\frac{ n }{ 2n })^{n}\]

Answer 3

Most of the problems that I have seen involving reindexing have reduced the index, but it looks like I'll need to do the reverse here, and I'm not so sure how to do that satisfactorily.

Answer 4

i dont think you can, not by just changing n

Answer 5

You just take a rubix cube and solve it.
