Determine the radius and interval of convergence of the following power series. x6x⁹ x12 5! + -- 2! 3! 4! + -11 Find the interval of convergence. Select the correct choice below and fill in the answer box to complete your choice. OA. The interval of convergence is (Simplify your answer. Type an exact answer. Type your answer in interval notation.) OB. The interval of convergence is {x: x=}. X= (Simplify your answer. Type an exact answer.)

#15 state wether the series converges or diverges and what test used. ive tried many so any test that works will be okay.

Find the interval of convergence of the power series. (Be sure to include a check for convergence at the endpoints of the interval. If the interval of convergence is an interval, enter your answer using interval notation. If the interval of convergence is a finite set, enter your answer using set notation.) >(-1)" x6n + 5 6n + 5 n = 0
