Final answer:
The number 2000 falls between the two consecutive integers 1999 and 2001 as it is an integer itself.
Step-by-step explanation:
When considering consecutive integers, we are looking at numbers that follow one after the other without any spaces in between, such as 1, 2, 3, and so on.
So, to find out which two integers 2000 lies between, we identify the integer that comes just before 2000 and the one that comes just after.
Since 2000 is an integer itself, the two consecutive integers it lies between are 1999 and 2001.
