To find the odd man out in the given sequence 1, 5, 14, 30, 42, 55, 91, we need to analyze the pattern or relationship between the numbers.

Let's examine the differences between consecutive terms:

5 - 1 = 4 14 - 5 = 9 30 - 14 = 16 42 - 30 = 12 55 - 42 = 13 91 - 55 = 36

Looking at the differences, we can observe that they are not following a consistent pattern. However, the difference between 42 and 30 is 12, which is different from the other differences. This suggests that 42 is the odd man out.

Therefore, the correct answer is B) 42.

To find the odd one out in the given sequence, let's analyze the numbers:

42, 56, 72, 90, 110, 132, 150

Looking closely, we can observe that all the numbers in the sequence are increasing. However, one number does not follow this pattern.

Let's check each option:

A. 110 - This number follows the increasing pattern and does not stand out.

B. 90 - This number also follows the increasing pattern and does not stand out.

C. 150 - This number breaks the increasing pattern. The previous numbers increase by a difference of 14, 16, 18, 20, 22, and 24, respectively. However, the difference between 132 and 150 is 18, which is not consistent with the pattern. Therefore, the number 150 is the odd one out.

D. 132 - This number follows the increasing pattern and does not stand out.

Therefore, the correct answer is C) 150.
