The deltas between the terms follow a pattern here ( -3, -20, +16),( -3, -13, +9),( -3, -6, +2).
May be this what she used here to get to the answer.
So the last three numbers should be
14 - 3 = 11
11 - 6 = 5
5 + 2 = 7.
In the question there is only 2 question marks so 11,5 should be the answer.

The 2nd and 3rd deltas in the sets of three increase and decrease by 7 respectively.

Answer 2

11, 5... hope this helps!
