This site is supported by donations to The OEIS Foundation.

 Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing. Other ways to donate

 OFFSET 1,1 COMMENTS The terms are found by finding the digit sum of twin prime pairs and then dividing the digit sum by the total number of digits in the twin primes combined. LINKS Chris Caldwell, The First 1,008 Twin Primes EXAMPLE The digit sum of the twin primes pairs 41 and 43 is 12 which when divided by 4 gives 3, a prime, which is the first term in the sequence. The digit sum of the twin prime pairs 347 and 349 is 30 which when divided by 6 gives 5, a prime, which is the fourth term in the sequence. The digit sum of the twin prime pairs 431 and 433 is 18 which when divided by 6 gives 3, a prime, which is the fifth term in the sequence. The digit sum of the twin prime pairs 857 and 859 is 42 which when divided by 6 gives 7, a prime, which is the ninth term in the sequence. CROSSREFS Cf.
