Twin Prime Numbers are the set of two numbers that have exactly one composite number between them. They can also be defined as the pair of numbers with a difference of 2.

We can check if a prime number by adding and subtracting 2 from the number. 5 is the only prime number that has two twin primes: {3, 5} and {5, 7}.

To check 61, we add and subtract 2 from it.

Addition:


61+2=63

Subtraction:


61-2=59

63 is not a prime number, as it can be divided by 3. 59, however, is a prime number.

Therefore, THE TWIN PRIME OF 61 is 59.
