Answer:
The sequence has a common difference of 1/16, which means to get the next term, we need to add 1/16 to the previous term.
The next four terms would be:
9/32 (1/4 - 1/16)
5/16 (1/4 + 1/16)
11/32 (5/16 + 1/16)
3/8 (11/32 + 1/16)
So the full sequence is: 1/16, 1/8, 3/16, 1/4, 9/32, 5/16, 11/32, 3/8, ...
