Do there exist three 2-digit primes such that:
- Any two of the three, averaged, produce another prime, and
- The average of all three is prime
(In reply to

Okay, there are tons of these sequences!
Dropping the requirement that the first two primes be consecutive primes, the first 10-tuple of an arithmetic progression of primes comes pretty early:
{199,409,619,829,1039,1249,1459,1669,1879,2089}
... okay, I will try to leave this alone. Thanks Brian.
