If r is common ratio then first three terms can be as \"system%28x%2C+xr%2C+xr%5E2%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Last term is also \"y=xr%5E2\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"r%5E2=y%2Fx\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"r=sqrt%28y%2Fx%29\"
\n" ); document.write( "
\n" );
