Ok it's me again. I'm am working on problems that involve describing number patterns. I've figured them all out but two.
Here are the two strings or numbers
7,9,13,19,27,;;;;
and
256, 16, 4, 2
Any help?

7+2=9+4=13+6=19+8=27 and so on. Basically it starts by adding 2 then for each next one it adds 2 so plus 2 then plus 4 and so on.
256 divided by 8=16 divided by 4=4 divided by 2=2 for this one the amount divided keeps getting cut down by 50%. Hope I helped. =) 
ahhhh thank you, thank you, thank you!
