 OFFSET 1,1 COMMENTS It is easy to see that all terms > 83 are divisible by 3. Likewise all terms except 38 are congruent to 3 (mod 8). - Franklin T. Adams-Watters, Jun 17 2015 LINKS K. D. Bajpai, Table of n, a(n) for n = 1..10000 FORMULA a(n) = A069484(n) + A001248(n+2). - Michel Marcus, Nov 08 2013 EXAMPLE a(1)=38 because 2^2 + 3^2 + 5^2 = 38.
