Identifying the Wrong Number
To find the wrong number in the series provided, we need to carefully analyze the pattern and relationships between the numbers given.

Series Analysis:
- 13 + 1 = 14
- 14 + 13 = 27
- 27 + 18 = 45
- 45 + 23 = 68
- 68 + 41 = 109
- 109 + 68 = 177

Finding the Wrong Number
As we can see, the pattern in the series involves adding consecutive prime numbers starting from 1. However, when we try to apply this pattern to the last number in the series, 177, it does not fit.
Therefore, the wrong number in the series is 177.

Correct Answer: d) 177

In each of the following questions the series begins with an unnumbered figure on the extreme left. One and only one of the five numbered figures in the series do not fit into the series. The two unnumbered figures one each on the extreme left and the extreme right fit into the series. You have to take as many aspects into account as possible of the figures in the series and find out the one and only one of the five numbered figures which does not fit into the series. The number of that figure is the answer.Study the following question.In this question the number of lines in the figures goes on increasing one from left to right. If we go by this aspect of the number of lines’ only then there is no wrong figure in the series. But if we also consider the ‘manner’ in which the ‘number of lines’ in the figures goes on increasing from left to right we come to know that the figure No. 4 does not fit into the series. Therefore, 4 is the answer.
