Series Pattern is +3, +5, +7, +9.

So next number = 25+11 = 36

5. Which fraction will come next, \begin{aligned} \frac{1}{2}, \frac{3}{4}, \frac{5}{8}, \frac{7}{16}, ? \end{aligned}

  • \begin{aligned} \frac{11}{32} \end{aligned}
  • \begin{aligned} \frac{9}{28} \end{aligned}
  • \begin{aligned} \frac{9}{30} \end{aligned}
  • \begin{aligned} \frac{9}{32} \end{aligned}

Answer: Option D

Explanation:

Numerators of the fractions in the given sequence are getting increased by 2, i.e. 1+2,3+2,5+2, so next will be 7+2 = 9

Denominators of the fractions in the series is getting doubled, 2*2 = 4, 4*2 = 8, 8*2 = 16, no next will be 16*2 = 32

So resulting fraction will be
\begin{aligned}
\frac{9}{32}
\end{aligned}
