Yes
Develop an algorithm to display all prime numbers from 2 to 100. Give both the pseudocode version and the flowchart version. Convert your pseudocode into a Java program.
There is a proof that there is no such formula for generating all the prime numbers. Best, TSA
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.

A) Here's an example of a flowchart and pseudocode that could be used to display the prime numbers between 1 and 10000: Flowchart: START Set up an array of numbers from 1 to 10000 Set an empty array to store the prime numbers Set i = 2, the first prime number For each number in the array, check if it is divisible by i If it is divisible by i, it is not a prime number and move to the next number in the array If it is not divisible by i, it is a prime number and add it to the prime numbers array Increase i by 1 and go back to step 4 Repeat steps 4 through 7 until i is greater than the square root of 10000 Display the prime numbers array END

A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies

A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
