calculus  interval of convergence
infinity of the summation n=0: ((n+2)/(10^n))*((x5)^n) .. my work so far. i used the ratio test = lim (n>infinity)  [((n+3)/(10^(n+1)))*((x5)^(n+1))] / [((n+2)/(10^n))*((x5)^n)]  .. now my question is: was it ok for me to

please help me...for the power series summation of n^4x^n/2(n1)factorial....find the radius and interval of convergence... so far i am guessing that radius is equal to x and interval of convergence is (infinty to positive
