1.) Suppose that (6x)/(10+x)= sum C_n(X^(n))

n=o to

Find: (what I got, but was wrong)

C_0= 0

C_1= 6/11

C_2= 1

C_3= 18/13

C_4= 24/14

Find: Radius of convergence R, I got 10.

I've been struggling with setting any sum problem up.

2) Find the interval of convergence for the given power series: n=1

(x-5)^(n)/n(-10)^(n)

The series is convergent from x=___, left end included (Y,N)___

to x=___, right end included (Y,N)___

any info and pointers is GREATLY appreciated, thank you :)
