Sorry, not quite sure what you mean by the "Nth term", but if I remember my maths correctly, the formula for the perimeter of a circle is pi x diameter. From your information, the perimiter would be 1000m, so the diameter would be 1000 / pi, = 318.5m. So I'd say the answer would be a circle with diameter of 318.5m.
