नीचे दी गई श्रृंखला में अगला अंक कौन-सा होना चाहिये ? 2, 1, (2/3), (1/2), ?

Correct Answer: (D) 2/5

Expressing each term with numerator 2, the series is $\frac{2}{1}=2$$\frac{2}{1}$ = 2, $\frac{2}{2}=1$$\frac{2}{2}$ = 1, $\frac{2}{3}$$\frac{2}{3}$, $\frac{2}{4}=\frac{1}{2}$$\frac{2}{4}$ = $\frac{1}{2}$. The denominator increases by 1 in each successive term, so the fifth term is $\frac{2}{5}$$\frac{2}{5}$.
