The problem is:(adsbygoogle = window.adsbygoogle || []).push({});

a(n+1) = ( a(n)^2 +16) / ( 2a(n) + 6) converges to the limit:...?

for n>=1 and a(1) = -10

Also note (n+1) and (n) are subscripts

Also another question..:

If f(x) is a function that is 8 times continuously differentiable such that the coefficient of x^5 in its 8th MacLaurin polynomial is 0.2, then f^5(0) =

If someone could solve these and explain what they are doing it would be extremely helpful. My textbook has no questions like this so I'm completely lost.
