The general term of the sequence $\dfrac{1}{2}, \dfrac{2}{3}, \dfrac{3}{4}, \ldots$ is —

a $\dfrac{n}{n+1}$
b $\dfrac{n-1}{n+1}$
c $\dfrac{n+1}{n}$
d $\dfrac{1}{n}$

ব্যাখ্যা

Each term has numerator equal to its position $n$ and denominator one more, $n+1$ : $\dfrac{1}{2}, \dfrac{2}{3}, \dfrac{3}{4}, \ldots$ . Hence the general term is $\dfrac{n}{n+1}$ .
