aaron is skipping stones across a pond.(A "skip"is a short bounce in the water.)The first stone skips 1 time, the second skips 2 times, the third stone skips 4 times,and the fourth stone skips 8 times.
if this patten continues,how many total skips will the 10th stone make? how many total skips will have been made?
what is the patten?if yo knew the number of the stone,such as 11th,or n,how would you figure out how many skips it would take?
1st -- 1 times = 2^0
2nd -- 2 times = 2^1
3rd --- 4 times = 2^3
I am sure you can see the pattern
