\n" ); document.write( "Note: for an arithmetic sequence: \"a%5Bn%5D+=+a%5B1%5D+%2B+%28n-1%29d\"
\n" ); document.write( "where d is the difference between the terms of the sequence
\n" ); document.write( "nth term formula for the arithmetic sequence: 20,17,14,11
\n" ); document.write( "In this example d = -3
\n" ); document.write( " \"a%5Bn%5D+=+20+-+%28n-1%293\" \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
