3. sohailiftikhar

it's 8

4. sohailiftikhar

look at these triangles there are two sequences one is 18,19 and other is 21,22

6. sohailiftikhar

look at first triangle sum of all numbers are 18 and that of third 19. but for second triangle sum is 21 and for fourth it should be 22 like 18,21,19,22etc

7. phi

yes, I would go with 3

8. phi

it is a bit painful finding that pattern.

9. sohailiftikhar

guys look at my reason ...

10. sohailiftikhar

the two sequences I am sure about 8.

11. mathmath333

18,21,19,22 doesn't make as sense as it would have been 18,19,20,21

12. mathmath333

will go with 3

13. phi

The "correct answer" with these types of problems is they look at the answers "smart" people come up with. If they get the same answer from a bunch of them, that becomes the official answer.

14. mathmath333

yea interview question it is

15. sohailiftikhar

so how you can say 3 huh ?

16. phi

If Loser finds the same pattern, that seals the deal.

17. sohailiftikhar

this is smart thinking that i have guessed there are to patterns here ..

18. Loser66

Yes, I am!! I got 3 also, on a way just a little bit different from @ganeshie8

19. phi

ok, and I saw the pattern also. I know you two are smart and I am so-so. Still that makes 3 who see the same thing.

20. sohailiftikhar

21. mathmath333

yea looser is smart boy

22. phi

Unfortunately, I don't see an easy way to teach how to do this

23. sohailiftikhar

ganish never told that it's 3 ok

24. Loser66

Yes, he does

26. sohailiftikhar

so you have no idea how you do this that's how intelligent solves their problem huh ?

27. sohailiftikhar

where he said that it's 3 loser?

28. Loser66

ok, he didn't, just my "assume"

29. sohailiftikhar

lol

30. phi

Loser, how do you reason it. (fyi, I saw the same thing as gan)

31. mathmath333

yea show ur cards looser

32. sohailiftikhar

you are just throwing things in air loser ..lol

33. ganeshie8

there are no wrong answers for these reasoning questions, nobody can prove me wrong if i say that i found a pattern which gives $$\pi$$ as the answer

34. imqwerty

LOL yes i agree :D @ganeshie8

35. Loser66

This is what I did for the first one 6*2 -2*2 =12-4 =8 for the second one 7*3 -3*5 = 21-15 =6 for the third one 7*2-2*4 =14 - 8 =6 Hence the last one is 6*3-3*5 =18 -15 =$$\color{red}{3}$$

37. phi

I like it. there is more of a pattern to your approach. start at the top, multiply adjacent numbers, move clockwise. of course, if you factor out the common multiple, e.g. 6*2- 2*2 = (6-2)*2 and we get the other pattern: (top - left) * right
