You can put this solution on YOUR website!
google \"sum of a geometric series\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the ratio (between consecutive terms) is -1/3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can find the number of terms in the series from ___ -1/2 r^k = \"last term\"
\n" ); document.write( "___ where k is the number of terms beyond -1/2 and r is -1/3
\n" ); document.write( "___ k should be around 10
\n" ); document.write( "
\n" );
