Question

Write all the twin prime numbers from $51$to $100$.

Answer 1

Twin prime numbers from $51$to $100.$

Two prime are the prime numbers whose difference is two.

Now, the prime numbers between $51$and $100$ are:

$53,59,61,67,71,73,79,83,89,97.$

Here, prime number whose difference is $2$:

$$\begin{gathered} 61-59=2 \\ 73-71=2 \end{gathered}$$

Thus, twin primes between $51$and $100$ are $\left(59,61\right),\left(71,73\right)$.
