What is the general term of prime numbers?

A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

What is the nth term of prime numbers?

Triangle Numbers 1, 3, 6, 10, 15, nth term = ½ n (n + 1) Prime Numbers 2, 3, 5, 7, 11, 13, etc.

What is the general term in number patterns?

The nth (or general) term of a sequence is usually denoted by the symbol an . a1=2 , the second term is a2=6 and so forth. A term is multiplied by 3 to get the next term. If you know the formula for the nth term of a sequence in terms of n , then you can find any term.

What is the algorithm to find prime numbers?

In mathematics, the sieve of Eratosthenes is a simple, ancient algorithm for finding all prime numbers up to any given limit. It does so by iteratively marking as composite (i.e., not prime) the multiples of each prime, starting with the first prime number, 2.
