- We think there is a theorem ( By Weierstrauss ? ) on this subject
- but we cannot find
- it. Can anyone out there tell us if the following is true?
-
- =======================================================================
-
- If the terms, a , of a series have the following property:
- n
-
- a A
- n+1 1 n
- ------ = 1 - ----- + ----- as n -> oo
- a n n
- n
-
-
-
- where A -> 0 as n -> oo
- n
-
-
-
-
- then does sum of the a diverge ?
- n
-
-
- Thanks in advance for the help.
