Immediately after what? More information is needed.
Because it immediately follows another prime number.
... 47, 53, 59 ... As you can see there is no Prime Number 50 in the partial list to the left, unless it is 53?
It is 53
It is 53
If the number is odd, you can immediately eliminate 2.
The prime number which comes immediately before 30 is 29.
2056 is an even number. The only even prime number is 2.
The prime number which comes immediately before 30 is 29.
The number 356 is not prime. You should immediately notice that it is an even number, divisible by two, therefore it cannot be prime. Only odd numbers can be prime.
The Prime Numbers either side of 50 (which is not a prime number) is 47 and 53.Note: 50 is not a prime number because 50 can be divided by 2 and 5 making it a composite number.
An eager prime is a prime number that is immediately followed by another prime number. For example, the number 3 is an eager prime because the next number, 5, is also prime. This concept highlights the occurrence of consecutive prime numbers and their distribution within the set of natural numbers. Eager primes can be of interest in number theory and the study of prime gaps.
A prime number is a number whose only positive integer factors are itself and 1. Since 2056 ends in a 6, you know the number is divisible by 2 and therefore cannot possibly be prime.
