add x
\n" ); document.write( "(32+x)/(16+x)=(56+x)/(32+x), since the ratios are the same between adjacent numbers.
\n" ); document.write( "1024+64x+x^2=896+72x+x^2
\n" ); document.write( "128=8x
\n" ); document.write( "x=16
\n" ); document.write( "so the geometric sequence is 32, 48, 72, and the ratio is 1.5
\n" ); document.write( "
\n" );
