​Relationship with other odd numbersEdit

The numbers beforeEdit

  • The previous odd number, 11, is a prime number.
    • There are no odd numbers between 11 and 13. As a result, they are twin primes.
  • The odd number previous to 11 is 9. 9 is a square number.
  • The odd number previous to 9 is 7. 7 is a prime number.
    • 7 and 13 are six numbers apart; therefore, they are sexy primes.

The numbers afterEdit

  • The next odd number, 15, is not a prime number. It is divisible by 3 and 5.
  • 17, the odd number following 15, is a prime number.
    • 13 and 17 are four numbers apart; therefore, they are cousin primes.
  • 19, the odd number following 17, is a prime number.
    • 13 and 19 are six numbers apart; therefore, they are sexy primes.

TriviaEdit

  • The fear of number 13 is called Triskaidekaphobia, which was founded at 1911.
