- a(n) = 3^n - 2.at n=10A058481
- a(n) = (2^n - 1)^11 - 2.at n=2A098939
- Numbers missing from A109681.at n=10A109682
- a(1)=1; then successively add 1, divide by 2, add 2 and then total up the last 4 terms.at n=40A112027
- Partial sums of A162436.at n=20A164123
- Start at 1, then add the first term (which is one here) plus 1 for the second term; then add the second term plus 2 for the third term; then add the third term to the sum of the first and second term; this gives the fourth term. Restart the sequence by adding 1 to the fourth term, etc. (From a sixth grade math extra credit assignment).at n=30A167051
- a(n) = (2 - 3^n)*(-1)^n.at n=11A168589
