Answer 1

Step-by-step explanation:

1,First writing all the prime numbers from 51 to 100, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. From the above prime numbers we can say only two twin prime pairs exist, those are (59,61) and (71,73). Twin primes between 51 and 100 are (59,61) and (71,73).

2,the difference between two co-prime numbers is 2 then, the numbers are said to be twin prime numbers. Hence, the twin prime numbers from 1 to 50 are (2,3), (5,7), (11,12), (17,19) and (29,30).
