D Correct answer
Explanation

The first differences are +2, +6, +14, +30. The second differences (differences of differences) are +4, +8, +16, which double each time. The next second difference should be 32, so the next first difference is 30+32=62. Therefore, 54+62=116. This is a geometric progression in the second-order differences.
