9 +7 = 16
16 + 7 = 23
23 + 7 = 30
As it is;
51 + 7 = 58,
58 + 7 = 65,
As answer D is correct.
16 + 7 = 23
23 + 7 = 30
As it is;
51 + 7 = 58,
58 + 7 = 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.

According to me;
3^2 - (-1)*0 = 9
4^2 - 0*1 = 16
5^2 - 1*2 = 23
6^2- 2*3 = 30
7^2- 3*4 = 37
8^2 - 4*5 = 44
9^2 - 5*6 = 51
Amd similarly,
10^2 - 6*7 = 58 &
11^2 - 7*8 = 65.
Thanks!

3*3 + 0 = 9.
3*5 + 1 = 16.
3*7 + 2 = 23.
3*9 + 3 = 30.
3*11 + 4 = 37.
3*13 + 5 = 44.
3*15 + 6 = 51.
3*17 + 7 = 58.
3*19 + 8 = 65.
Hence the answer is 58, 65.
