Explanation:

- The sequence starts with 2.

- Each number in the sequence seems to be derived from a pattern involving the previous number.

- Let's analyze the numbers:

- Start with 2, multiply by 1 and add 2 = 4

- Multiply by 2 and add 3 = 11

- Multiply by 3 and add 4 = 37

- Multiply by 4 and add 5 = 153

- The expected number here is 153, but 151 is present.

- It seems like there is a consistent pattern that was broken at 151.

- Correct Answer: 151
