not sure your ninth pattern really works mathematically/logically. it increases by 1,2,2,4,2 in order so 4 would not be the next increase and yet that is what is accepted. plus way too much time given for so few patterns.

The ninth one doesn't work by adding numbers, it is the list of the prime numbers.

It's probably this sequence: http://oeis.org/A000124. The formula is a(n)=n(n+1)/2+1.
