How do you find the nth term on fractions? - Answers

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 :)
