COMMENTS
| Contribution from Lekraj Beedassy (blekraj(AT)yahoo.com), Apr 30 2010: (Start)
Sum of next n primes starting with the n-th prime.
For sum of next n primes starting with the (T(n) + 1)-th prime, or A000124(n)-th prime = A078721(n), {T(n)=A000217(n)}, see A007468(n). (End)

EXAMPLE
| Sum of 3rd prime to 5th prime = 5+7+11, hence a(3) = 23; sum of 4th prime to 7th prime = 7+11+13+17, hence a(4) = 48.
