2 + 3 = 5
7 - 2 = 5

As the number 2 is the only even prime number then a difference of 1 occurs only between 2 and 3. All other prime numbers are odd and therefore the minimum difference between successive prime numbers is 2.
No. For two integers to have a difference of 3, one must be odd and one must be even. The only even prime number is 2. That means the only pairs of prime numbers that have a difference of 3 must be 2 and another number. The only numbers that could have a difference of 3 are -1 and 5. Since -1 is not a prime number, that is not a pair that meets this description. Since 5 is a prime number, the pair of 2 and 5 is the only possible pair of prime numbers that can have a difference of 3.
The difference between prime and composite numbers is simple. Prime numbers have only two factors, 1 and itself. Composite numbers are divisible by more than two numbers

3 and 2 are the only prime numbers with a difference of 1.
Any prime number, a prime number is a number of which the only factors are it and itself.
Numbers with only two factors, the number itself and one, are called prime numbers. Examples of prime numbers are 2 (which is the only even prime number) and 17.
The only prime numbers with a difference of 1 are the numbers 2 and 3. More consecutive numbers are not possible, since one of the two would have to be even - and an even number is divisible by 2, and therefore not a prime number (2, of course, is a prime number, but larger even numbers are not).The most you can expect with larger prime numbers is a difference of 2. Very large such "prime twins" are known; a few are 3 and 5; 101 and 103, but much larger ones are known, as well. It is not yet known whether there are an infinite number of twin primes.The only prime numbers with a difference of 1 are the numbers 2 and 3.

There can only be one largest two-digit prime number.
No, 2 is a prime number.
A prime number is a number that is only divisible by 2 numbers, 1, and itself. So 11 is a prime number because it is only divisible by 2 numbers, but you wouldn't say it is a prime number of 22. There are no prime numbers of a number.
Here are some facts about prime numbers:1. Prime numbers have exactly two factors - 1 and the prime number itself.2. The only even number that is prime is 2.3. There are an infinite number of prime numbers.4. Every number can be uniquely represented as a prime number or a product of prime numbers.
