Answer:
After 16 nights girl will have 2 to the power of 16 or 65,536 pennies.
Step-by-step explanation:
The first night there were 2 pennies. So a1 = 2 (2 to the power of 1)
Each night the number doubles:
a2 = 2 * 2 = 4 (2 to the power of 2)
a3 = 2 * 2 * 2 = 8 (2 to the power of 3) ...
Finally a16 = 2 to the power of 16 = 65,536 pennies.
