Answer 1

12, 48, 192, 768, 3072/

Answer 2

Well, I think this is much better viewed in python:
#Start at 12. Create a pattern that multiplies each number by 4. Stop when you have 5 numbers
req_list = [12]i = 1while i < 5:    for b in req_list:        b = b * 4    i += 1    req_list.append(b)print(req_list)
