B Correct answer
Explanation

The sequence is an AP with a = 7 and d = 9. The difference between the 30th and 27th term is (a + 29d) - (a + 26d) = 3d = 3 * 9 = 27.

AI explanation

This sequence is an arithmetic progression with a common difference of 9, calculated as 16 minus 7. The difference between any two terms is simply the common difference multiplied by the number of steps between them. The gap between the 27th and 30th terms is 3 steps, so the difference is 3 times 9 equals 27, making the correct option B.
