You can put this solution on YOUR website!
You can also use the fact that if a series of (positive) terms $\"sum%28a%5Bn%5D%2C+n+=+1%2C+infinity%29\"$ converges, then the general term $\"lim%28+x-%3Einfinity%2C+a%5Bn%5D%29+=+0\"$ . By contraposition, since the general term $\"a%5Bn%5D\"$ approaches infinity, the series itself diverges. \n" ); document.write( "
