There are 35 pairs of twin prime numbers totaling 69 numbers (prime number 5 appears twice in the twin pairs) between 0 and 1000.
They are members of the set of numbers of the form 7*k where k is an integer which takes 1000 different values..
The prime numbers (factors) of 1000 are: 2 and 5
There are 168 prime numbers between 1 & 1000.
1000 numbers. From 19,500 to 20,499 all round to 20,000

There are infinitely pairs that will work but my favorite is 1000 divided by 8 .
500.5 Because: 1+2+3+.......998+999+1000 Add 1 to 1000 equaling 1001. This makes a pair. There are 500 more of these so 500 pairs. So 1001x500= 500500 Finally divide it by 1000 because there are 1000 numbers. (1000-1=999+1=1000) Concluding the answer to be 500.5 :)
There are a total of 890 numbers between 110 and 1000 inclusive - 445 of these are odd, and 445 are even.
There are infinitely many possible pairs. Some pairs are: 1 and 500 1000 and 1/2 sqrt(5) and 100sqrt(5)
431 and 669.

There are infinitely many pairs of numbers. Some examples: 1 * 8400 1000 * 8.4 2400 * 3.5 sqrt(1500) * sqrt(47040)
