Ignoring the alternating signs for the moment, for the sequence
\n" ); document.write( "
\n" ); document.write( "\"5\", \"8\", \"13\", \"20\", \"29\", ...
\n" ); document.write( "
\n" ); document.write( "the nth term is given by \"x+=+n%5E2+%2B+4\"
\n" ); document.write( "
\n" ); document.write( "We account for the alternating signs by multiplying each term by \"-1%5En\"
\n" ); document.write( "
\n" ); document.write( "so the formula for the nth term in the original sequence is
\n" ); document.write( "
\n" ); document.write( "\"x+=+%28-1%29%5En+%2A+%28n%5E2+%2B+4%29+\"
\n" ); document.write( "
\n" ); document.write( "and the next two terms are 40 and -53.
\n" ); document.write( "
\n" ); document.write( "
\n" );
