They are the multples of 2*3 or 6.
6,12,18,...
Since 2000/6 = 333.3333333...
The largest multiple of 6 that does not exceed 2000
is 333*6 or 1998, so the list is
6,12,18,...,1998
If we divide every number in the list by 6, we get
this list:
1,2,3,...,333
There are 333 in that list so there are also 333 in
the list 6,12,18,...,1998.
Answer: 333
