these are really hard to remember but dont worry its MUCH more easier when you understand what "prime" actually means! :)
You find the first 20 prime numbers and add them together. There is no formula for generating a sequence of prime numbers and so none for the series of their sums.You find the first 20 prime numbers and add them together.

The median for the first 20 prime numbers would be 30. This is because the middle two numbers of the first 20 prime numbers are 29 and 31. To find the median from this, we need to find the average of these two numbers. This is 30.

The first prime above 20 is 23, and then all others (29 is the next).

The first two consecutive prime numbers that have a difference of 20 are the numbers 887 and 907.
The first prime above 20 is 23, and then all others (29 is the next).
These are the prime numbers 1-20 2,3,5,7,11,13,17,19
23, 29 & 31.

2/5 of the numbers from 1 to 20 are prime numbers
The prime factors of 20 are 2x2x5.
10 and 20 are composite numbers, not prime numbers. The prime factorization of 10 is 2 x 5. The prime factorization of 20 is 2 x 2 x 5.
The prime numbers of 20 are 2, 2 and 5. (2*2*5 = 20)
The only even prime number is 2. It happens twice in the prime factorization of 20.
There are two prime numbers between 20 and 30 which are 23 and 29
The prime numbers between 20 and 30 are 23 and 29.
There are 12 composite (and 8 primes) in the first twenty whole numbers. So the probability of randomly choosing a non-prime is 12/20 or 60%.
The prime numbers between 10 and 20 are 11, 13, 17, and 19.
7 + 13 = 20 Note that there are no two prime numbers x and y that multiply to 20.
The prime numbers between 15 and 20 are 17 and 19. To find the product of these two prime numbers, you simply multiply them together: 17 x 19 = 323. Therefore, the product of the prime numbers between 15 and 20 is 323.
All the numbers from 2 to 19 are multiples of prime numbers.
