Composite
The twin primes that are greater than 20 but less than 30 are (23, 25) and (29, 31). However, since 25 is not prime, the only valid twin primes in that range are (29, 31). Twin primes are pairs of prime numbers that have a difference of two.
The next three primes greater than 41 are 43, 47, and 53.
All natural numbers greater than 1 the product of 1 and one or more primes.
There are 168 prime numbers between 3000 and 4000. Prime numbers are positive integers greater than 1 that have no positive divisors other than 1 and themselves. The primes in this range include numbers like 3001, 3011, and 3019, up to 3991.
There is no particular characteristic that is common to such numbers other than they are positive integers greater than or equal to 4.
There are an infinite number of primes greater than any number given.
They are called co-primes.
The twin primes that are greater than 20 but less than 30 are (23, 25) and (29, 31). However, since 25 is not prime, the only valid twin primes in that range are (29, 31). Twin primes are pairs of prime numbers that have a difference of two.
The longest string of consecutive numbers that are primes is two digits long, consisting of 2 and 3 only. There are no other consecutive numbers that are primes because no even numbers greater than 2 are primes.
52 is composite. No even numbers greater than 2 are primes.
The next three primes greater than 41 are 43, 47, and 53.
No.

There are some patterns, but none that can help you determine, in all cases, whether the number is a prime or not.For example: * All primes except 2 are odd numbers. However, not all odd numbers are primes. * All primes greater than 3 are of the form 6n - 1, or 6n + 1. However, not all numbers of this form are primes.
There is no particular characteristic that is common to such numbers other than they are positive integers greater than or equal to 4.
All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum. 11 cannot be written as the sum of two primes. 13 = 2 + 11. 17 cannot be written as the sum of two primes. 19 = 2 + 17.
