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.)

Actually what I meant to say here was "every term is over 3" for 3 terms, "every term is over 5" for 5 terms and "every term is over 8" for 8 terms.

I wrote the solution to reflect these parts, is that OK?
