To find out how much each person saved, we need to add up their savings over the 6 weeks:

Mary: 2 + 4 + 8 + 16 + 32 + 64 = 126
Jane: 10 + 12 + 14 + 16 + 18 + 20 = 90
Tom: 7 + 13 + 19 + 25 + 31 + 37 = 122
Andy: 3 + 6 + 9 + 12 + 15 + 18 = 63

Therefore, from smallest to largest amount saved, the order is: Andy, Jane, Tom, Mary.

The code word is AJTM.
