Is there a formula for prime numbers

Witrynaprime number theorem, formula that gives an approximate value for the number of primes less than or equal to any given positive real number x. The usual notation for this number is π ( x ), so that π (2) = 1, π (3.5) = 2, and π (10) = 4. The prime number theorem states that for large values of x, π ( x) is approximately equal to x /ln ( x ). Witryna11 lip 2024 · "While the formulae in this article are unsuitable for application to problems in prime number theory, they at least provide definite answers to the questions (see e.g. Hardy and Wright, An Introduction to the Theory of Numbers, § 1.5): Is there a formula for the nth prime number? Is there a formula for a prime, given the preceding prime?"
