Question

What are twin primes?write all the pairs of twin primes between 50 and 100.

Answer 1

 first few twin prime pairs are: (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73)

Answer 2

Answer:

(59, 61) and (71, 73).

Step-by-step explanation:

Given : Numbers between 50 and 100.

To find : What are twin primes?

Write all the pairs of twin primes between 50 and 100.

Solution :

A twin prime is a pair of prime numbers whose difference is exactly 2.

For example - (59,61) both are prime numbers, and the difference is 61-59=2

But (2,3) is not twin prime because of the special nature of 2 being the only even prime, it is defined to not count.

The pairs of twin primes between 50 and 100.

First find the prime numbers between them

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

So, there are two pairs between 51 and 100,

⇒ (59, 61) and (71, 73).
