999 (whole) numbers. THere are the same number whether they are counted in ascending, descending or other order.
All numbers between 1000 and 2000, or anywhere else, can be expressed as a power of another number.
3000
1000+1000 1000x2
3 integers: 1200,1500,1800
1950 is between 1000 and 2000. 2000 is much closer, only 50 away. 1000 is 950 away. So 2000 is the answer.

Do a search on Google, for "prime numbers" table, or "prime numbers" list, and you will surely find something.I cannot tell precisely without looking up a table or doing some longish calculus but as a gross estimatation there should be about this many prime numbers between 1000 and 2000:2000 / ln(2000) - 1000 / ln(1000) =~ 263 - 144 = 119Actual number of primes between 1000 and 2000 should be a little above 119(in the range [140, 160] i think)

They are 1024, 1125 and 1372.
1000 to 2999 inclusive so 2000 numbers.

A palindromic number is a number that remains the same when its digits are reversed. Between 1000 and 2000, the possible palindromic numbers have the form "ABBA" where A and B are digits from 1 to 9. There are 9 options for A (1-9) and 10 options for B (0-9), but we exclude the case where A is 0. Therefore, there are 9 * 10 = 90 palindromic numbers between 1000 and 2000.
-1000
M-MM
They are all the 4 digit numbers starting with 1 and ending with 1, 3, 5, 7 or 9. Since there are 500 of them, I will not list them.
