List all prime numbers between 200 and 300 which the double sum of digits is 5 (Solved). Written by Administrator Sunday, 17 October 2010 18:31 List all prime numbers between 200 and 300 which the double sum of digits is 5. Answer: The primes between 200 and 300 are: 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 281, 283 and 293. The sum of the digit to lead one number, and so the double sum if necessary of the previous primes are: 2+1+1=4, 2+2+3=7, 2+2+9=13,1+3=4, 2+3+3=8, 2+3+9=14,1+4=5, 2+4+1=7, 2+5+1=8, 2+5+7=14,1+4=5, 2+6+3=11,2+6+9=17,8, 2+7+1=10,1, 2+8+1=11,2, 2+8+3=13,4, 2+9+3=14,5 The solution are: 239, 257 and 293. Please understand that each number lead to another summing its digits. 5 means Change ... or great change. While 3 is acceleration. FTHumanEvolutionCourse is looking to release a collection of books for the BASIC of Preparation for Young people in the collection of "Forgotten Science and New Age". Therefore, we will choose a number between these three. Please note that 2010=2+1=3 (Acceleration) and 2012=2+1+2=5 (Change) ... are the actual and coming year. 2011=>4 leads to Gaia (Mother).
