C. Caldwell, The first 1000 primes

FORMULA

a(n)=A034963(4n-4). [From R. J. Mathar, Apr 20 2009]

EXAMPLE

a(1) = 17 = 2 + 3 + 5 + 7 = prime (1) + prime (2) + prime (3)+ prime (4).

a(2) = 60 = 11 + 13 + 17 + 19 = prime (5) + prime (6) + prime (7)+ prime (8).

a(3) = 120 = 23 + 29 + 31 + 37 = prime (9) + prime (10) + prime (11)+ prime (12)....

MATHEMATICA
