THere are 7 people sitting next to each other in a row. They have been ask to get up and re sit themeslves to either to go sit back to their original spot or the spot next to them either right or left. In how many ways can they be seated?!?

Would it be 7 times 6 times 5 times 4 times 3 times 2? I'm not entirely sure but that's what I would have done in your situation.
