The first three terms of the GP are \r
\n" ); document.write( "\n" ); document.write( "x, s, y,...\r
\n" ); document.write( "\n" ); document.write( "The common ratio r is equal to both s/x and y/s, and \"s%2Fx+=+y%2Fs\", or \"s%5E2+=+xy\".\r
\n" ); document.write( "\n" ); document.write( "==> \"s+=+sqrt%28xy%29\" or \"s+=+-sqrt%28xy%29\"\r
\n" ); document.write( "\n" ); document.write( "==> Common ratio r is equal to either \"sqrt%28xy%29%2Fx+=+sqrt%28y%2Fx%29\", or \"-sqrt%28y%2Fx%29\"\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
