Question 9

A series is given, with one number missing. Choose the correct alternative from the given ones that will complete the series.

1.5, 9/4, 3, ? , 4.5, 21/4

Solution

The pattern followed is that in each number $$\frac{3}{4}$$ is added.

1.5 $$+\frac{3}{4}$$ = $$\frac{9}{4}$$

$$\frac{9}{4}$$ $$+\frac{3}{4}$$ = $$\frac{12}{4}=3$$

3 $$+\frac{3}{4}$$ = $$\frac{15}{4}$$

$$\frac{15}{4}$$ $$+\frac{3}{4}$$ = $$\frac{18}{4}=4.5$$

4.5 $$+\frac{3}{4}$$ = $$\frac{21}{4}$$

=> Ans - (A)
