Sir divergent

Post by Cezar Lupu »

Sa se arate ca sirul \( (a_{n})_{n\geq 1} \), definit prin \( a_{1}>0 \) si \( a_{n+1}=a_{n}+\frac{1}{na_{n}},\forall n\geq 1 \), este divergent.
An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer. The bartender says “You’re all idiots”, and pours two beers.
