You have to double both amount of pennies and number of square, so it will look like it:
square 1 - 1
square 2 - 2
square 3 - 0
square 4 - 4
squares 5 to 7 - 0
square 8 - 8
square 16 - 16
square 32 -32
square 64 - 64
what in total gives 127
1 penny on the 1st square, 2 pennies on the 2nd, 4 on 4th, 8 on 8th, 16 on 16th, 32 on 32nd and 64 on 64th gives 1.27$
still, i think it would've been funnier if he had just gone with the arithmetic sequence and given him 20$.
