How else can the sequence for row 1 be written? notice: square a: 1 penny = 20 square b: 2 pennies = 21 square c: 4 pennies = 22 how many pennies would be on the square labeled h?

128

Explanation:

It is apparent that the number of pennies on each square doubles the number of pennies on the previous square.

That ca be seen in this way:

Square     number of pennies
A              1
B              1 × 2 = 2
C              2 × 2 = 2² = 4
D              4 × 2 = 2³ = 8
F               2⁴ = 16
E               2⁵ = 32
G               2⁶ = 64
H                2⁷ = 128

221,500 is the answer
