%N Sum of successive sums of successive primes: a(n) = s(n) + s(n+1) where s(n) = prime(n) + prime(n+1) (A001043).

%C The first term is the only term that has a chance of being prime.

%F a(n) = A001043(n) + A001043(n+1) = A000040(n) + 2*A000040(n+1) + A000040(n+2). - _M. F. Hasler_, Jun 02 2017

%e The sums of the first two pairs of successive primes are 5 and 8. 5+8 = 13 is the first term in the sequence.
