If you double a penny everyday and add it to the previous day's total for 30 days?

This would be doubling the the previous days amount for 30 days: (1)1 - (2)2 - (3)4 - (4)8 - (5)16 - (6)32 - (7)64 - (8)128 - (9)256 - (10)512 - (11)1024 - (12)2048 - (13)4096 - (14)8192 - (15)16384 - (16)32768 - (17)65536 - (18)131072 - (19)262144 - (20)524288 - (21)1048576 - (22)2097152 - (23)4194304 - (24)8388608 - (25)16777216 - (26)33554432 - (27)67108864 - (28)134217728 - (29)268435456 - (30)536870912 Then I re-read the question (and quoted the main piece): If you double "a penny" everyday and add it to the previous days total for 30 days Which means the 1st day you would have doubled your penny. Then the next day you double 1 of the 2 pennies which give you 3 pennies and add it to the previous days total which gives you 5 and so forth and so on....: (If you want to get technical on how the question was written!) (1)2 - (2)5 - (3)11 - (4)23 - (5)48 - (6)97 - (7)195 - (8)391 - (9)783 - (10)1567 - (11)3135 - (12)6271 - (13)12543 - (14)25087 - (15)50175 - (16)100351 - (17)200703 - (18)401407 - (19)802815 - (20)1605631 - (21)3211263 - (22)6422537 - (23)12845065 - (24)25690131 - (25)51380263 - (26)102760527 - (27)205521055 - (28)411042111 - (29)822084223 - (30)1644168447 Can I have a round of applaud please...(clapping)...! Thank You and Good Night! I think the question states that if you double a penny every day not doubling the total of penny's there! There for you have a common denominator of 2 every day! then you add previous days amount! day 1(2) day 2(4) so forth and so on! with a total of 60 penny's So there for double a penny meaning double 1 penny every day for 30 days witch is 2 pennys every day plus the total from the day before!
