There isn't any pair in question, so why the answers are in pair? '" How can I solve that 65? Please anyone explain me.

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,
As answer D is correct.

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!

We can solve in another way also.
every third no. should be added with 21, other than that each no should be added with 7.

It,s very simple. . .
9*1=9-0=9
9*2=18-2=16
9*3=27-4=23
9*4=36-6=30
9*5=45-8=37
9*6=54-10=44
9*7=63-12=51
9*8=72-14=58
9*9=81-16=65
so d ans is 58 n 65
9*1=9-0=9
9*2=18-2=16
9*3=27-4=23
9*4=36-6=30
9*5=45-8=37
9*6=54-10=44
9*7=63-12=51
9*8=72-14=58
9*9=81-16=65
so d ans is 58 n 65

Its so easy:-
9+7=16
16+7=23
23+7=30
30+7=37
37+7=44
44+7=51
So the answer is 58(51+7)and65(58+7)
Isn't it easy one??
Have a nice day!!!

9 16 23 30 37 44 51... every number added by 7.
So 51+7 = 58.
58+7 = 65.
Answer is: 58 65.
So 51+7 = 58.
58+7 = 65.
Answer is: 58 65.
