Are you sure that's how it's written? Are there no other information regarding that question?
If that's all that is given, there is no unique answer.
Help me understand why is the right answer:
It doesn't help to say "That's exactly how it's written."
There must be some other clues somewhere . . .
Are those 9-digit numbers? .
Are they sets of 3-digit numbers? .
We can only guess at the intent of the problem.
Here's one guess . . .
Suppose the middle number is a function of the other two numbers.
. . That is: .
Then there are several brizillion possible functions.
Here's a function that produces answer
. . . . .
That is, subtract the two outer numbers, and multiply by 6.
But this function produces answer
And this function produces answer
Conclusion: The author took too much cough syrup . . .
I still maintain that the problem is grotesquely silly . . .

To make my point, I made up a similar problem
. . without giving you the answer.

Hello again ,
I obviously havent made myself clear in my previous thread , first i meant thanks very much for taking your time replying to me , after that i just copied your suggested answear and just wrote that i think thats the right logic that they are looking for me to find ( the one you've given , not like i just found it myself ! ) and i yea i agree with you that is incredibly silly and makes no sense at all ,its from an expample test that includes 5 different moduls - maths , literature,history etc ,the maths one include 10 tasks with few " logical " problems , u only have a minute to asnwear each question as well , .... oh and i have the answeasr after each test so thats how i know its C the right answear !
and again thanks for your help .......
