Here is simple addition series which starts with 9 and addition of 7 that is 9+7=16, 16+7=23, .... 51+7=58, 58+7=65.

So 58 65 is correct answers.

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.

Mallikarjun said: (Oct 28, 2011)  
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

Radhika said: (Nov 9, 2011)  
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!!!

Mallikarjune garu learn simple ways to solve solution.

Shammi said: (Dec 27, 2011)  
You are right babu.

Ramkumar said: (Jun 8, 2013)  
9 16 23 30 37 44 51... every number added by 7.

So 51+7 = 58.
58+7 = 65.

Answer is: 58 65.

Sarabjit said: (Jul 3, 2014)  
As add 9 by every number. The answer should be 59, 66.

Jay said: (Oct 29, 2014)  
7*1+2=9
7*2+2=16
7*3+2=23
7*4+2=30
7*5+2=37
7*6+2=44
7*7+2=51
7*8+2=58
7*9+2=65

Hi friends:

9+7=16.
16+7=23.
23+7=30.
30+7=37.
37+7=44.
44+7=51.
51+7=58.
58+7=65.

Answer = (58, 65).

Krishnababu said: (Feb 26, 2015)  
Hi friends.

9+7=16.
16+7=23.
....
....
....
44+7=51.
51+7=58.
58+7=65.

So answer is (58, 61).

Pradeep said: (Apr 27, 2015)  
9, 23, 37, 51, 65 this is 14 no difference or add.

Example : 14+9=23.

23 + 14 = 37.

37 + 14 = 51.

51 + 14 = 65.

16, 30, 44, 58.

16 + 14 = 30.

30 + 14 = 44.

44 + 14 = 58.

So answer is 58 65.

Rashmi said: (Jul 8, 2016)  
Here all numbers are added by 7 then it gives the answer so when we add 7 to 51. It gives 58 and then 58 +7= 65.

V.Mahesh Kumar said: (Sep 28, 2016)  
Add 7 between the numbers like 9 + 7 = 16, to the last number is 51 + 7 = 58.
Again add last digit 58 + 7 = 65.

Alad said: (Oct 23, 2016)  
Thanks for explaining the logic.

Immu said: (Nov 1, 2016)  
The given series is the combination of even and odd numbers by adding 7.

A K Tiwari said: (Nov 16, 2016)  
9 + 14 = 23
23 + 14 = 37
37 + 14 = 51
51 + 14 = 65 & 16 + 14 = 30, 30 + 14 = 44, 44 + 14 = 58 answer 58 65.

G Mahesh Babu said: (Nov 19, 2016)  
9, 16, 23, 30, 37, 44, 51......

Adding 9 and substraction with 2
9 + 9 = 18 - 2 = 16
16 + 9 = 25 - 2 = 23
23 + 9 = 32 - 2 = 30
30 + 9 = 39 - 2 = 37
37 + 9 = 46 - 2 = 44
44 + 9 = 53 - 2 = 51
51 + 9 = 60 - 2 = 58
58 + 9 = 67 - 2 = 67.

So answer 58, 67.

Vikash Kumar said: (Jan 30, 2017)  
Yes, the correct answer is 58, 65.

Geet said: (May 10, 2017)  
How 65 came? Explain.

Utkarsh said: (May 25, 2017)  
9 +7 = 16
16 + 7 = 23
23 + 7 = 30

As it is;

51 + 7 = 58,
58 + 7 = 65,
As answer D is correct.

Aman said: (Apr 28, 2018)  
I agree with you @Mallikarjun.

Piyush said: (May 4, 2018)  
Thank you all for explaining the answer.

Balachander said: (Jul 15, 2018)  
Yes, the correct answer 58, 65.

Vandan said: (Dec 24, 2018)  
Here, it is a simple addition series which starts with 9 and addition of 7 that is 9+7=16, 16+7=23, .... 51+7=58, 58+7=65.

So, 58 65 is the correct answer.

Sanap Karuna Sudam said: (Mar 14, 2020)  
Adds 7 every no then answer is 58 65.

Pranshu Barnwal said: (May 14, 2020)  
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!

Siva Koteswararao said: (Jan 8, 2021)  
In this problem, the pattern is adding 7.

Then 51 + 7=58, 58 + 7 = 65.

Asj said: (May 25, 2021)  
There isn't any pair in question, so why the answers are in pair? '" How can I solve that 65? Please anyone explain me.
