a(n) is the number of possible choices for the first n terms of a "mean-central" sequence, where a monotonically increasing sequence of positive integers {b(n)} is called "mean-central" if for each positive integer k, the arithmetic mean of the first b(k) terms is exactly b(k). A383192

Consider all integer triples (i,j,k), j >= k > 0, with binomial(i+2,3)=j³+k³, ordered by increasing i; sequence gives k values. A54207

a(1)=1. a(n) = a(n-1) + sum of the triangular numbers which are among the first (n-1) terms of the sequence. A100963
