Ok--I know to double the answer each time until 30--which would be:5,368,709.12

Is there an equation to make this easier?

Thanks

Sort of. Notice that on the nth day, the amount of money that day is 2^(n-1 ) Then notice the amount of money made to date (look at the above figures) is 2^(n-1) -1.

So the total the miner earns in thirty days...

2^29 + 2^29 -1= 2^30 -1 cents.

check that for n= 4, and n=5

Thank you!
