The sum of all the numbers between 1,000 and 2,000 (which means 1,001 through 1,999) is 1,498,500. If you meant 1,000 through 2,000 then the result is 1,501,500.
All numbers between 1000 and 2000, or anywhere else, can be expressed as a power of another number.

All the odd numbers between 1 and 2001.
All numbers that are divisible by 5 and 9 are multiples of their lcm which is 45. So the question boils down to which multiples of 45 are between 1000 & 2000. 1000 ÷ 45 = 222/9 2000 ÷ 45 = 444/9 Thus the solution is the multiples of 45 from 23 to 44 which are: 1035, 1080, 1125, 1170, 1215, 1260, 1305, 1350, 1395, 1440, 1485, 1530, 1575, 1620, 1665, 1710, 1755, 1800, 1845, 1890, 1935, 1980
All numbers between 1000 and 2000, or anywhere else, can be expressed as a power of another number.
what are all of the composite numbers between 1000 to 3000?
-1000
Ten. They are all of the form 1xx1 where x can take the values 0,1,2,...,9
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.
