The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
The only two consecutive numbers that are both prime are 2 and 3. Since there are no other even prime numbers (other than 2), there are no more pairs of consecutive prime numbers. Therefore, the term "twin primes" usually refers to pairs of prime numbers that are 2 numbers apart. Examples are (3, 5), (5, 7), (11, 13), (101, 103), and many others more. It is not currently know whether there are infinitely many twin primes.
There are no prime numbers greater than 10 that add up to 29. Since all prime numbers greater than 2 are odd numbers, no two prime numbers greater than 2 can have an even number for their sum.
Only 1 pair of prime numbers, 2 and 5, have a difference of 3. All prime numbers greater than 2 are odd so will have an even difference.
A single number cannot be relatively prime. Any pair of numbers between 50 and 100 of which one is a prime will be relatively prime. There are 728 pairs of numbers that are relatively prime and I have neither the time nor patience to list them all!
The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
31+5, 19+17, 7+29, 23+13 That's all of them I think??

you where no help at all
They are relatively prime.
19 + 79, 31 + 67 and 37 + 61
There are an infinite number of pairs of prime two apart, classified as "twin primes". For lists, see the link.
No, as all prime numbers are odd, excluding 2, and when you add two odd numbers you get an even number. This even number can't be a prime number as it will be divisible by 2. 101 and 31 are both prime, but 101+31 is 132.
