If the sequence is geometric, type in the common ratio. If it is not, type in no.

\r\n" );
document.write( "To find out if it is geometric, \r\n" );
document.write( "\r\n" );
document.write( "1. divide the second term by the first term.\r\n" );
document.write( "\r\n" );
document.write( "\"100%2F500=1%2F5\"\r\n" );
document.write( "\r\n" );
document.write( "2. divide the third term by the second term.\r\n" );
document.write( "\r\n" );
document.write( "\"20%2F100=1%2F5\"\r\n" );
document.write( "\r\n" );
document.write( "3. divide the fourth term by the third term.\r\n" );
document.write( "\r\n" );
document.write( "\"4%2F20=1%2F5\"\r\n" );
document.write( "\r\n" );
document.write( "They are all the same, so it's a geometric sequence,\r\n" );
document.write( "and the common ratio, r, is \"1%2F5\"\r\n" );
