Question from kyrie, a student:

what are the first 3 terms of this sequence

n-2 divided by n squared

Hi Kyrie.

The first term will be the value of the expression when you substitute
"1" in for "n":

(n-2) / (n2)

(1-2) / (12)
= -1 / 1
= -1

So the first term is -1. Try it with n=2 and n=3 to find the next two
terms in the sequence.
