\n" ); document.write( "The common ratio is

\n" ); document.write( "48/72 = 72/108 = 108/162 = 2/3

\n" ); document.write( "Because the value 162 is for x=1, one form of the exponential function is

\n" ); document.write( "\"y+=+162%282%2F3%29%5E%28x-1%29\"

\n" ); document.write( "Since 162 is (2/3) of 243, another form of the expression is

\n" ); document.write( "\"y+=+243%282%2F3%29%5Ex\"

\n" ); document.write( "
\n" ); document.write( "
