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

    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

    it is a bit painful finding that pattern.

    the two sequences I am sure about 8.

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

    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.

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

    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.

    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

    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 =\(\color{red}{3}\)

    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
