Question: ->>>> n If we try to take use ratio test to calculate radius and level of convergence, 2 We will get lim = (x+1)

->>>> n If we try to take use ratio test to calculate radius and level of convergence, 2 We will get lim = (x+1) 1. But if we plug X=-2 and series, they diverge. X=0 into the My question: How to find the radius and level of convergence here? Thank you!
