Abstract :
earliest works on the prime numbers are as old as 1500 BC yet as of the present, no known simple formula can distinguish the prime numbers from the composite numbers. The number of primes not greater than any natural number z is given by a function denoted by π(z), known as prime counting function. The value of which is approximated using the prime number theorem. It can be also computed using a function based on the work of B. Riemann. This article includes, derivation of simple formula of function that counts prime upto any given number z with essential calculations and an example to understand. The presented theoretical work is also aimed to derive the general formula for the nth term of the prime number series which is an exact formula for the value of nth prime. The nth prime can be computed using the derived formula and the algorithm presented in this article.
