 A219255 Numbers n for which prime(n) divides at least one sum of two consecutive terms in sequence {f_m(k)}, defined in A224523. 1
 1, 2, 3, 5, 6, 7, 8, 10, 17, 23, 24, 25, 34, 36, 37, 45, 51, 120, 124, 219, 231, 244, 251, 2034, 2057, 3121, 4176, 5185, 9492 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 COMMENTS Places of the last elements of runs of the same terms in A224523 are in the sequence. Whether these sequences coincide one to another? LINKS EXAMPLE 7 is in the sequence, since prime(7)=17 and sequence {f_7(k)} is periodic with period {1,1,2,3,5,8,13,21,2,1,3,4,7,11,18}, such that sum of terms 13+21=34 is divisible by 17.
