First attachment shows my question regarding convergence
s econd attachment shows my quick question about natural numbers
The most common formal test for convergence is D'Alembert's Ratio Test: If Σur is a series of positive terms and limn→punun+1=p then if p<1Σur converges if p>1Σur diverges If p=1 the test is inconclusive.

Many Thanks for the responses :
would you say this second bit is expected at AS level - I've never been taught this test before at school LOOL.

Where did this 'spec' come from that is referred to in your attachments?
Formal tests for convergence aren't taught for A level as far as I'm aware, with the possible exception of the OCR MEI board - they sometimes look at quite advanced concepts as part of FM.
