LINKS

Table of n, a(n) for n=1..49.

FORMULA

a(n) = A161151(2*n)/2

a((2*n-1)*2^p) = 2^(2*p+2)*n - 2*2^(2*p) + 2^p, p >= 0.

MAPLE

nmax:=49: for p from 0 to ceil(simplify(log[2](nmax))) do for n from 1 to ceil(nmax/(p+2)) do a((2*n-1)*2^p) := 2^(2*p+2)*n - 2*2^(2*p) + 2^p od: od: seq(a(n), n=1..nmax);
