Ten primes, each less than 3000, form an arithmetic progression. Find them.

Congrats, Charlie -- you beat me to it by 27 seconds! (I decided to have one final look at my list of primes to confirm  before posting, which I did before yours appeared).  We used different computer languages, but to the same effect.  Check the primes from 3 up, and the even increments which could be added 9 times without exceeding 3000.   There are 429 primes from 3 to 2999 inclusive.
