The sequence given is 2, 3, 6, 11, 18. To find the 6th term, we can observe that each term is obtained by adding a certain number to the previous term.

When we subtract the second term (3) from the first term (2), we get 1. Similarly, when we subtract the third term (6) from the second term (3), we get -3. The pattern continues, with the differences being 5, 7, 9 for subsequent terms.

To find the 6th term, we need to add the difference of 9 to the previous term, which is 18. Therefore, the 6th term in the sequence is 27.

Option 2, which states that the 6th term is 27, is the correct answer.

Alert - correct answer should be 27
