According to me:
The solution is;
9 * 2 - 2 = 16.
9 * 3 - 4 = 23.
9 * 4 - 6 = 30.
9 * 5 - 8 = 37.
9 * 6 - 10 = 44.
9 * 7 - 12 = 51.
9 * 8 - 14 = 58.
9 * 9 - 16 = 65.
Then the answer is = 58 65.

Pattern Analysis:
Common Difference: Each term increases by 7:
16 − 9 = 7.
23 - 16 = 7.
and so on
General Formula: The n-th term can be expressed as:
7n+2.
Next Two Terms:
8th term:
7 × 8 + 2 = 58.
9th term:
7 × 9 + 2 = 65.
Answer: 58 and 65.
