They are 165001 and 174999.
Many schools will teach that 165000 should be rounded up to 170000 but this is incorrect since it introduces an upward bias. The IEEE standard 754 is to round up to an even digit. See also en.wikipedia.org/wiki/Rounding#Round_half_to_even

The smallest number would be 29500. The largest number would be 31499.
The wording of this question seems confusing. 5700 rounded to the nearest thousand would be 6000. So you appear to be looking for the largest and smallest whole numbers that would round to 6000.The smallest whole number that would round to 6000 would be 5500. 5499 if rounded to the nearest thousand would be 5000.The largest whole number that would round to 6000 would be 6499. 6500 if rounded to the nearest thousand would be 7000.

To solve this, you have to consider what the largest and smallest numbers could be to cause the ten thousand's place to round to a 0.404,444 is the largest, because if you round to the ten thousand's place, it will still be 400,000. If any of the 4s becomes a 5, it will round up to 410,000.394,445 is the smallest, because if you round to the ten thousand's place, it will round up to 400,000
