\n" ); document.write( "The nth term is $\"%28-1%29%5En\"$ assuming the pattern of {-1, 1, -1, 1, ...} repeats like that forever.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "n = 1, $\"%28-1%29%5En+=+%28-1%29%5E1+=+-1\"$
\n" ); document.write( "n = 2, $\"%28-1%29%5En+=+%28-1%29%5E2+=+%28-1%29%2A%28-1%29+=+1\"$
\n" ); document.write( "n = 3, $\"%28-1%29%5En+=+%28-1%29%5E3+=+%28-1%29%2A%28-1%29%2A%28-1%29+=+-1\"$
\n" ); document.write( "n = 4, $\"%28-1%29%5En+=+%28-1%29%5E4+=+%28-1%29%2A%28-1%29%2A%28-1%29%2A%28-1%29+=+1\"$
\n" ); document.write( "And so on.
