3. I think
Because you take the total number of problems (48) and divide that by 2 = 24. Then divide that by 2 = 12. And divide that by 2= 6. And divide that by 2 = 3.
He needs to complete 3 problems on the first day for the number of problems completed to double each day for 5 days to equal 48.
Andrew is making a plan to complete a class math assignment. He has 48 problems to complete over 5 days. He decides to complete the assignment is such a way that his total number of completed problems doubles every day. He realizes that that number must be 48 by the end of the fifth day.
How many problems does Andrew need to solve on the first day?
