a= (n^2-5n+6)/(n^2+n+1)
using the definition only prove the sequence(a) is convergent and find its limit?
what does this prove by definition means? is it same as when proving a limit?
any help is welcome. thanks
It seems the poster is asking how to use this definition to prove his result. Not the actual definition.
Experimentation suggests that . We want to show can be made as small as we want. Meaning,a= (n^2-5n+6)/(n^2+n+1)
What I wrote is a hint, complete the arugment thyself.
