Expert Answer:

 
Directly, you can say the total number of natural numbers between 500 and 1000 are 501.
 
Method:
 
500, 501, 502, .... 1000.
 
Since the difference between the two consecutive numbers are same.
 
This is an A.P.
 
Here, a = 500, d = 1 and an = 1000.
 
an = a + (n - 1)d 
 
→ 1000 = 500 + (n - 1)1
→  500  = n - 1 
→  n = 501
