• a(n) = 3^n - 2.at n=11A058481
• a(1)=1; then successively add 1, divide by 2, add 2 and then total up the last 4 terms.at n=44A112027
• Semiprime nearest to 3^n. In case of a tie, choose the smaller.at n=12A117416
• Partial sums of A162436.at n=22A164123
• 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=33A167051
