• Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 50.at n=14A031728
• a(n) = 225*n^2 + 15.at n=25A158557
• a(n) = Sum_{i=1..n} nac(i,n) where nac(i,n) is the n-th i-bonacci number. The n-th i-bonacci number here is equal to 1 for the first i terms, with subsequent terms equaling the sum of the previous n terms.at n=18A345372
