Lorenzo Navarro · Answer 1

The answer is divide by 2.

128 : 2 = 64

64 : 2 = 32

32 : 2 = 16

16 : 2 = 8

The others can't work because:

128 : 4 = 32 (This is not the next term, this is the one after - therefore it's wrong)

128 - 8 = 120 (This isn't even a term in the pattern.)

128 - 64 = 64

64 - 64 = 0 (This only works for the first term, after that, you get 0 - not a term in the pattern.)
