The numbers $a$ and $b$ are prime and satisfy $\dfrac{a}{a+1}+\dfrac{b+1}{b}=\dfrac{2k}{k+2}$ for some positive integer $k$. Find all possible values of $b-a$.
The concept of "Prime Pairs" involves finding pairs of prime numbers that have a specific difference, represented by the equation b-a. These pairs are also known as twin primes.
Prime pairs have been studied by mathematicians for centuries and have been linked to important concepts such as Goldbach's conjecture and the distribution of prime numbers. They also have applications in cryptography and number theory.
Goldbach's conjecture states that every even number greater than 2 can be expressed as the sum of two prime numbers. Prime pairs play a crucial role in understanding and potentially proving this conjecture.
There are various methods that can be used to find prime pairs, including sieving methods, probabilistic methods, and more advanced techniques such as the Goldston-Pintz-Yıldırım method. These methods involve identifying patterns and relationships between prime numbers.
Prime pairs have practical applications in fields such as cryptography and computer science. They are also useful in understanding the distribution of prime numbers, which has implications in data encryption and security.
