The chapter Series deals us with the group of figures which forms a series by using a certain rule.

Obeying this rule, the figures depicts a change step by step.

This chapter consists of the following types of problems and to solve each type, a student first needs to identify the rule or pattern. A student may come across two types of series:

1. To choose a figure which would continue the given series of figures.

2. To choose a missing figure that is capable to establish a series.

**EXAMPLE**

**1. Find the figure from the options which will continue the series established by the Problem figures.**

(a) (b)

(c) (d)

**Explanation (a): **

Area enclosed by black shaded region in top left circle, increases by \[45{}^\circ \] and rotates anticlockwise by \[45{}^\circ \] in each stage.

The same procedure happens for other circles.

So the correct option is (a).

**2. Choose the missing figure from the four options to substitute the question mark(?), so that a series is formed.**

(a) (b)

(c) (d)

**Explanation (c): **

We observe that the black shade in a circle moves 2 steps anticlockwise in each step.

So, the correct option is (c).
