%0 Journal Article %T On the Number of Primes in the Interval (<i>x</i>, 2<i>x</i>) by an Elementary Method %A Sudhindra B. Kittur %J Advances in Pure Mathematics %P 16-29 %@ 2160-0384 %D 2024 %I Scientific Research Publishing %R 10.4236/apm.2024.141002 %X An elementary formula to know the number of primes in the interval (x, 2x) close to the exact figure for a fixed x is given here. A new elementary equation is derived (a relation between prime numbers and composite numbers distributed in the interval [1, 2x]). An elementary method to know the number of primes in a given magnitude is suitably placed in the form of a general formula, and we have proved it. The general formula is applied to the terms of the equation, and a tactical simplification of the terms gives rise to an expression whose verification envisages scope for its further studies. %K Prime Numbers %K Composite Numbers %K Expression %K Integers %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=130423
