Study the following arrangement carefully and answer the questions given below.

$2 4 8 5 6 \mathrm{P} \mathrm{I} 3 @ 6 4 5 2 \# 9 7 1 3$

If all the symbols are dropped from the above arrangement, which of the following will be the twelfth from the right end of the above arrangement?

In the given questions there are two sets of figures. The figures in the first row are Problems Figures (four figures and one question-marked space) and those in the second row are Answer Figures indicated by numbers 1, 2, 3, 4, and 5. A series is established if one of the five Answer Figures is placed at the “question-marked space”. Question Figures form a series if they change from left to right according to some rule. The number of the Answer Figure which should be placed in the question-marked space is the answer. All the five figures i.e. four Problem Figures and one Answer Figure placed in the question-marked space should be considered as forming the series.
