How do you find the nth term on fractions?

Answer 1

if the answer, for example, was "FIND THE NTH TERM OF THESE NUMBERS" and they listed:

1, 1/4, 1/9, 1/16, 1/25...

then this is how I personally would go about it.

okay, so the first term is 1. write them all down like this:

1. 1

2. 1/4

3. 1/9

4. 1/16

5. 1/25

(it makes it easier to see which term is which)

as they are all over ONE, you can ignore the top number and focus on the bottom one --> and remember that 1 = 1/1.

square the N number; what do you get?

1*1 = 1

2*2 = 4

3*3 = 9

4*4 = 16

5*5 = 25

so we now have n^2 (N squared), but they aren't a fraction. *sad face*

this is where we take the expression N squared and we put a 1 over it (since all of the terms are over 1:

1/n^2 (one over N squared)

if the answers were all over 2, put -- 2 over [the expression to solve the denominator (bottom number)] -- and so on.

hope this helped :)
