Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 59th year, we have over 358,000 sequences, and we’ve crossed 10,300 citations (which often say “discovered thanks to the OEIS”).

Index entries for linear recurrences with constant coefficients, signature (8,40,-60,-40,8,1).

FORMULA

a(n) = (A000032(n))^5 = A000032(n)*A099923(n).

a(n) = L(5*n) + 5*(-1)^n*L(3*n) + 10*L(n), L(n) = A000032, the Lucas numbers.
