my problem is regarding sequences:(adsbygoogle = window.adsbygoogle || []).push({});

Sum first 20 terms of a=r^k-1

terms are 2, 4/3, 8/9,...

and ratio is 2/3

and r < 1 so its an inflated series

and 2(2/3)^19 = .009021859795

BUT it is an inflated series right? and my answer is the sum of the

first 20 terms which has to be larger than 2 right? so where am I

going wrong?
