C Correct answer
Explanation

The listed terms are 1, 2, 4, 7, 11, and 16, with successive differences 1, 2, 3, 4, and 5. The next difference is 6, so the seventh term is 16 + 6 = 22.

AI explanation

This sequence follows a pattern where each term increases by consecutive positive integers: 1, 2, 3, 4, 5, and 6. To find the 7th term, add 6 to the 6th term. This gives 16 + 6, which equals 22.
