The sequence is a geometric sequence:
\n" ); document.write( "1, 2, 6, 24, 120, 720,...
\n" ); document.write( "In general, the sequence can be expressed:
\n" ); document.write( "\"a%5Bn%5D+=+a%28n-1%29%2An\" or in words...
\n" ); document.write( "The nth term is equal to the previous term multiplied by n.
\n" ); document.write( "Let's check the 6th term (n=6):
\n" ); document.write( "\"a%5B6%5D+=+a%5B5%5D%2A6\" substitute \"a%5B5%5D+=+120\"
\n" ); document.write( "\"a%5B6%5D+=+120%2A6\"
\n" ); document.write( "\"a%5B6%5D+=+720\"
\n" ); document.write( "Or the 4th term:
\n" ); document.write( "\"a%5B4%5D+=+a%5B3%5D%2A4\" Substitute \"a%5B3%5D+=+6\"
\n" ); document.write( "\"a%5B4%5D+=+6%2A4\"
\n" ); document.write( "\"a%5B4%5D+=+24\"
\n" ); document.write( "
\n" );
