Define the sequence A where Asub1=a and Asubn=sqrt(a+Asub(n-1)) for n greater than or equal to 2(adsbygoogle = window.adsbygoogle || []).push({});

I need to determine what positive choices of a will make the sequence converge and to what limit. I also need to prove it.

I plugged some values into the sequence and found that it seems to converge for all positive real numbers but I don't know how find out what any given choice of a will converge to
