This type of questions begin with an un-numbered figure followed by five figures numbered from 1 to 5 and then again an un-numbered figure on the extreme right. These seven figure together form a series which starts at the first (un-numbered) figure and ends at the last (un-numbered) figure. However, one and only one of these figures does not fit into the series. The number of that figure is the answer.

In the above set of figures, the arrows are added to the right and left sides alternately. But in the third figure the arrow which was to be added to the right. Hence, the answer is (3).
