# Twin prime numbers explained

What are twin prime numbers? Have you heard about this numbers before and whether prime numbers and twin primes have any relation? Yes, it has some relation. I will explain this relation while giving the definition of twin primes. Actually, from prime numbers, we are going to define the twin prime numbers. So first we need to know what are prime numbers then you can understand twin primes concept. I hope that everybody knows about prime numbers so directly I will move on to explain twin primes.

## Definition of twin prime numbers:

Two prime numbers are called twin prime numbers if the difference between them is 2. So take any two prime numbers what you know then check whether the difference between them is 2 or not. If it is 2 then the prime numbers are called twin primes otherwise they are not twin prime numbers.

Example:

(3,5) (5,7) (11,13), …………

Consider the prime numbers 3 and 5. As the difference between these two prime numbers is 2 so (3,5) are called twin primes. Similarly (5,7) and (11,13) are also twin primes. Not only these three still we have so many twin primes. ### List of Twin prime numbers from 1 to 100:

(3,5)

(5,7)

(11,13)

(17,19)

(29,31)

(41,43)

(59,61)

(71,73)

From the above twin primes list, we can say that there are 6 pairs of twin primes from 1 to 50 and from 51 to 100 there are only 2 pairs.

#### List of Twin prime numbers from 100 to 200:

(101,103)

(107,109)

(137,139)

(149,151)

(179,181)

(191,193)

(197,199)

From 100 to 151 there are 4 pairs of twin primes and from 152 to 200 there are 3 pairs.

##### List of Twin prime numbers from 200 to 300:

(227,229)

(239,241)

(269,271)

(281,283)

From 200 to 250 there are 2 pairs of twin primes and from 251 to 300 there are 2 pairs.
