In a geometric sequence, $\"a%5B1%5D+=+4\"$ and $\"r+=+2\"$
\n" ); document.write( "The first four terms would be:
\n" ); document.write( "4, 8, 16, 32,...
\n" ); document.write( "Check:
\n" ); document.write( "The common ratio is given as 2 and this means that the ratio of consecutive terms $\"a%5Bn%5D%2Fa%5Bn-1%5D+=+2\"$ .
\n" ); document.write( " $\"8%2F4+=+2\"$
\n" ); document.write( " $\"16%2F8+=+2\"$
\n" ); document.write( " $\"32%2F16+=+2\"$ \n" ); document.write( "

\n" );
