Given: first day amount=$3,000,000.
It is given that amount double that amount the next day.
Note: The double amount is added to the amount present initially.
Each time we need to add $3,000,000 to the double amount to get the final amount for a particular day.
For second day amount will be 3,000,000+ double of 3,000,000, that is = 3,000,000 + 6,000,000 = $9,000,000.
Third day amount = 3,000,000 + 2*9,000,000 = $21,000,000.
Fourth day amount = 3,000,000 + 2*21,000,000 = $45,000,000.
Fifth day amount = 3,000,000 +2*45,000,000 = $93,000,000.
Sixth day amount = 3,000,000 +2*93,000,000 = $189,000,000 .
