For those who know the answer to this question, do not answer it and spoil it for everyone else:
Say I have a row of 1000 quarters which first start on heads and every 2nd quarter, I flip down to tails (so that would mean every 2nd, 4th, 6th, etc. quarter is flipped to tails). Say I do the same for every third number, every fourth number, etc. and all the way to 1000. Here is what I want you guys to solve:
1.) How many quarters are left on heads?
2.) Set up an equation to prove your answer.
I will give you guys 24 hours.
