• A nonlinear recurrence.at n=44A003073
• a(n) = n * [1 + sum(k=1 to n-1) prime(k)].at n=29A083719
• a(3n) = floor(43*2^n/28) - 1, a(3n+1) = a(3n) + 3*2^(n-3), a(3n+2) = floor(17*2^n/7 - 6/7) for n>=3.at n=44A123946
• a(n) = 1*4*7 + 4*7*10 + 7*10*13 + ... (n terms).at n=8A196513
• a(n) = n-1 for n <= 4, otherwise if n is even then a(n) = a(n-5)+2^(n/2), and if n is odd then a(n) = a(n-1)+2^((n-3)/2).at n=29A200310
