a twin number is a prime number that have a number between it for ex:3,5 in the middle there is a four
No, twin primes are pairs of prime numbers that have only one number between them which is a composite number. For example, (3, 5) and (11, 13) are twin prime pairs with the composite number 4 and 12 respectively between them.
A twin prime is a prime number that differs from another prime number by two.ex. (5, 7)The numbers two away from 23 are 21 and 25 which are both composite numbers.So in short, no 23 is not a twin prime.
A twin prime is a prime number that differs from another prime number by two. Except for the pair (2, 3), this is the smallest possible difference between two primes. Some examples of twin prime pairs are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31) and (41, 43). Sometimes the term twin prime is used for a pair of twin primes; an alternative name for this is prime twin. Hope this helps :)
The last known twin prime number as of now is 2996863034895, which is part of the twin prime pair (2996863034895, 2996863034897). Twin prime numbers are prime numbers that differ by 2. However, it is worth noting that there may be larger twin prime numbers that have not been discovered yet.
