 OFFSET 1,1 COMMENTS If prime(i) has level 1 in A117563 and 2*prime(i) - prime(i+1) = prime(i-k), then we say that prime(i) has level (1,k). LINKS Fabien Sibenaler, Table of n, a(n) for n = 1..10000 EXAMPLE 81569 = prime(7980) is a term because: prime(7981) = 81611, prime(7973) = 81527; 2*prime(7980) - prime(7981) = prime(7973).
