Find the least and the greatest numbers

Question

Find the least and the greatest possible numbers.

1. 90

2. 400

3. 5,000

4. 10,000

5. 200,000

Answer 1

If the question is, "What number in this sequence has the least value," then you can answer the question with 90. If the question is, "What number in this sequence has the greatest value," then you can answer 200,000. Neither of those conditions, however, are stated.

Answer 2

the least possible number is negative infinity

greatest number is positive infinity

but those are surreal numbers, not real

there is no largest or smallest real number, just ever larger or ever smaller without limit

pick any real number, there's always another real number larger or smaller
