A little about Lucky Number's

In number theory , a lucky number is a natural number in a set which is generated by a "sieve" similar to the " Sieve of Eratosthenes that generates the primes. Begin with a list of integers starting with 1:2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25

Lucky Number's In Math Term's

Every second number ( all even number's ) is eliminated , leaving only the odd integer's


1, 3, 5, 7, 9, 11, 13, 15, 17, 19 ,21 ,23, 25

The Next Step To Getting Lucky Number's

For the next step here is what you do: The second term in this sequence is 3. Every third number which remains in the list is eliminated. 1, 3, 7, 9, 13, 15, 19, 21, 23, 25 . The number's in purple so far are the non lucky number's so the one's in red are the lucky number's so far. Now you are done with the lucky number's .

Your lucky number's

The number's in purple are not your lucky number's and the number's in red are your lucky number's and those would be : 1,3,7,9,13,15,21,25,31,33,37,43,49,51,63,67,69,73,75,79,87,93,99,105,111,115,
