Homework Help: Convergence of (2n+3)/(4n+5)

  1. May 31, 2008 #1
    1. The problem statement, all variables and given/known data
    {an} is Convegent series then lim {an}=0
    O.K. But let {an}=(2n+3)/(4n+5) is Convegent series and lim an=1/2

    2. Relevant equations
    Elucidation for this look wanted

    3. The attempt at a solution

    Tell me what is a state that hates people who belong to it? :wink:

    Japanese to English translations sounds so much like this. But, I would also love to know.

    {an}=(2n+3)/(4n+5) is not convergent if you saying it is or someone said that.

    "Series" (in mathematics, not general English) means specifically a "sum" while "sequence" does not. (2n+3)/(4n+5) is a sequence that converges to 1/2. The series
    [tex]\Sum_{n=0}^\infty \frac{2n+3}{4n+5}[/tex]
    does NOT converge.

    From recent events I am tempted to say Myanmar.

    We know love
    Ten years ago you appreciate and respected by States
    The exchange of the same feeling
