Question

What are twin primes?

Write all pairs of twin primes between $50$ and$100$

Answer 1

Defination of twin primes and twin primes between $50$ and $100$:

Twin primes: Twin primes are the prime numbers that have a difference $2$ between them.

For example: $3$ and $5$ are prime numbers and the difference between them is of $2$ So they are twin primes.

Now, twin primes between $50$ and $100$ are $\left(59,61\right)$ and $\left(71,73\right)$.

Thus, twin primes are the prime numbers that have a difference $2$ between them, and twin primes between $50$ and $100$ are $\left(59,61\right)$ and $\left(71,73\right)$.
