Nth Term of Fractions How do I work out the Nth term of these fractions?
$$1,\frac{1}{4},\frac{1}{9},\frac{1}{16},\frac{1}{25},\dots$$
Would I need to change them all into decimals but that would be quite complicated and then go from there? Yes I can see a pattern, the denominators are squared numbers but what do I do after? I know that answer is going to have a $^2$ in it.
See if you can find any pattern in the fractions or their reciprocals.
$$T(n)= \frac{1}{n^2}$$ where $n$ is greater then equal to 0.
