Table of n, a(n) for n=1..26.

Formula

a(n) = A122102(n+1) - 16. - Michel Marcus, Nov 05 2013

Example

a(2)=706 because 3^4 + 5^4 = 706.

Maple

a:=proc (n) options operator, arrow: add(ithprime(j)^4, j=2..n+1) end proc: seq(a(n), n=1..26); # Emeric Deutsch, Oct 02 2007

Mathematica

c = 4; a = {}; b = 0; Do[b = b + Prime[n]^c; AppendTo[a, b], {n, 2, 1000}]; a {* Artur Jasinski *)
