%N If T(n)>=n is the nearest triangular number to n and p_n is the n-th prime, then a(n) is the least prime such that T(a(n)*p_n)-a(n)p_n is a triangular number
%C Conjecture. For n>=2 the sequence is nondecreasing.
%C The conjecture holds for the first 10000 terms. [_Charles R Greathouse IV_, Feb 21 2011]
