Tutorial Exercise Test the series for convergence or divergence. (-1)9n -211n +2 n =1 Step 1 To decide whether in9n -211n +converges, we must find lim 9n -2 n 0011n +2 n =1 The highest power of n in the fraction is 1 Step 29-11n-2 Dividing numerator and denominator by n gives us lim n 0011n +29n -2= lim n 009n -211n +2 ala Submit Skip (you cannot come back)
