Excellent way to follow these kind of problems. I use to take these as time consuming sums and skip it. I wont skip from now. Thanks Really a needful blog.

Still, I feel like I am missing something.. you said "k^2 = n(n+16).. now n is positive so n(n+16) is positive hence k is positive.." lets say, n=2 (taking the value of n from solution).. which gives k^2 = 2*18 = 36 or k = 6 and -6 Please correct me.. Thanks HS Hi Rahul,

you said “k^2 = n(n+16)..

lets say, n=2 (taking the value of n from solution)..
which gives
k^2 = 2*18 = 36
or k = 6 and -6

Please correct me..

Thanks

"but see this n is positive hence k is positive, thus n+8+k>n+8-k" my problem is if n is positive how come it can be inferred that k would also be positive.. as u have written in previous steps.. n+8+k= 32,16,8,4,2 taking, n+8+k =2 , implies n+k = -6 since n is a natural number, it only means k should be a negative number.. I then thought for a while and this thing came in my mind:- sum of the two factors is 2n+16.. and since n >= 1 so 2n+16>= 18 which gives us only two only values of 2n+16: 34, 20.. i don't know how correct I am... please correct me..

Hi Rahul,
In outtimed’s solution he/she has considered 1 as odd.Is that true?Isn’t 1 unique.If that is the case then the sum will be less by 125 i think.
