Let n = 153 You line up the coins (numbered 1 to n) heads up with #1 closest to you. step 1: you turn over every coin. step 2: go back to #1 and turn over every 2nd coin starting with coin #2. step 3: go back to #1 and turn over every 3rd coin starting with #3. and so on through step n: you turn over every the nth coin. How many times was the nth coin turned over and is it heads or tails and WHY? (HINT: It should be clear that to do this question you should not need to do every step !)
