Prime sequence (Posted on 2003-10-23) Difficulty: 4 of 5
What is the lowest arithmetic sequence of positive prime integers that has 3 terms? 5 terms? 8 terms?

What is the constant difference for the lowest N positive prime integers in arithmetic sequence?

What would the first term be for such a sequence?

(A prime sequence is "lowest" if the average of its terms is the lowest. If any are tied then it is the one with the smallest starting term.)

That same web site also shows that there is an 8-term sequence of primes that begins at just 11. However the difference between successive members is 1,210,230.
