two geometric means between $\"7\"$ and $\"15.379\"$ :\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"an=a1%28r%29%5En-1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"a4=7%28r%29%5E4-1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"15.379=7%28r%29%5E3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"15.379%2F7=r%5E3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2.197=r%5E3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"r=root%283%2C2.197%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"r=1.3\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"r=1.3\"$ is the ratio, so you multiply $\"7\"$ by $\"1.3\"$ (which equals $\"9.1\"$ ), giving you the $\"first\"$ of the two geometric means, and multiply $\"9.1\"$ by $\"1.3\"$ (which equals $\"11.83\"$ ) to get the $\"second\"$ of the two geometric means\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Final answer: $\"9.1\"$ , $\"11.83\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiplying $\"11.83\"$ by $\"1.3\"$ gives you $\"15.379\"$ , so it is correct.\r
