## AFleming42 Group Title Determine whether the sequence converges or diverges. If it converges, give the limit. 11, 22, 44, 88, ... one year ago one year ago

well the common ratio is r = 2... so the sequence is divergent...

sorry I have to go but for convergence the common ratio is -1 < r < 1 so if thats the case the limiting sum is $S_{\infty} = \frac{a}{1 - r}$
