So @Preswitch wanted me to make another lil game. It took me time to come up with something new, and I finally decided to make some sequences. You need to think logical to solve them so perhaps they are not so fun. I came up with all of them, except C. I. is a hard bonus. If you solve it then you are smart!

A. 1, 3, 7, 511, 255, 127, ..., 31, 63, 32767

B. 2, 3, 5, 7, 11, ..., 17

C. 1, 1, 2, 3, 5, 8, ..., 21

D. -36, -77, -80, -57, -20, ...

E. 9, 16, ..., 24, 25

F. 0, 5, 10, ..., 20, 25, 30

G. 1, ..., 27, 64, 125

H. 2, 8, ..., 32, 50

I. Which is the word?
