Prime Consecutive Numbers

Introduction to prime consecutive numbers:

A prime number is an number that has only two factors and is divisible only by 1 and itself, and by no other positive integer.The first few prime numbers are 2, 3, 5, 7, 11,13, 17, 19, 23, 29, 31 and 37.

The consecutive number is nothing but adjacent numbers for example the consecutive numbers of 2 is 3, even consecutive number between 1 to 10 is 2,4,6,8,10.

The prime consecutive number are of rare as the prime number were not of adjacent values normally. But there are two prime numbers that is also consecutive. the two and three are the only prime consecutive numbers. Let us see more about  prime consecutive numbers.

Discussion on Prime Consecutive Numbers

More about prime numbers:

A prime number is a natural number larger than 1 which cannot be expressed as the product of two smaller natural numbers.

Prime numbers were first studied rigorously by the ancient Greeks. One of the first theorems they proved was

Euclid’s theorem (˜ 300 BCE) There are infinitely many prime numbers.

Arithmetic progressions of primes

As we mentioned earlier, we are still unable to detect several types of patterns in the primes. However, we have made recent progress on one type of pattern, namely an arithmetic progression a, a + r, . . . , a + (k - 1)r.

In particular, for any given k, the primes contain infinitely many arithmetic progressions of length k. This result builds upon a number of existing results; for instance, in 1939, van der Corput showed that the primes contained infinitely many arithmetic progressions a, a + r, a + 2r of length three.

I am planning to write more post on find the prime factorization of 36, multiplying and simplifying rational expressions. Keep checking my blog.

More Discussion on Prime Consecutive Numbers

Let us take an example of number of prime numbers from the 1 to 1000 and try to find the number of prime consecutive numbers that can occur in that sequence.

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, 503, 509, 521, 523, 541, 547, 557, 563, 569, 571, 577, 587, 593, 599, 601, 607, 613, 617, 619, 631, 641, 643, 647, 653, 659, 661, 673, 677, 683, 691, 701, 709, 719, 727, 733, 739, 743, 751, 757, 761, 769, 773, 787, 797, 809, 811, 821, 823, 827, 829, 839, 853, 857, 859, 863, 877, 881, 883, 887, 907, 911, 919, 929, 937, 941, 947, 953, 967, 971, 977, 983, 991, 997.

Here if we notice the above given prime numbers from 1 to 1000 numbers. The ones digit of the prime numbers are all odd numbers except the 2, also the 2 and 3 are the consecutive numbers and also prime numbers.

The 2 and 3 are the only prime consecutive numbers as all the other higher values are  with odd values, however these may satisfy the condition of prime consecutive odd numbers. the consecutive number in the list of prime numbers do not occur.
