Assuming * means "multiplied by", notice that 2, 4, 6, 8, ... are all even; also notice that 1,3,5,7.. are each one less than an even number.

What, in terms of n, would you associate with an even number? What's one less than that even number? Remember that, for each n, you're multiplying them together.

Get it? :smile:
