Can someone explain this one? I got the 5,6 part but the 12 and 13 I could only get by some obscure logic.

im sorry i dont get it.....please help me! lol

I got half right.

The first of each pair is an acsending pattern:
1(+1=)2 (+1=)3 (+1=)4 (+1=)5(+1=)6 (+1=)7 (+1=)8.....+1..etc.

The next number in each pair increases in a pattern of +1,+2, +1, +3, +1, +4 etc...
5(+1=)6 (+2=)8 (+1=)9 (+3=)12 (+1=)13 (+4=)17 (+1=)18..... +5+1+6+1+7..etc.

So you end up with these pairs
1,5.. 2,6.. 3,8.. 4,9.. 5,12.. 6,13.. 7,17.. 8,18.. 9,23.. 10,24.. 11,30..

Oddly.. if that's how it's supposed to work my answer had a little bit more reasoning to it that than that answer but that's how I understand the answer given.

I hope I understood the explanation correctly and that made it a little clearer.

yeah, that helped quite a bit, i corrected this teaser because previously, it didnt make any sense, but i couldnt really change the numbers given. it didnt have an explanation, so i made one up, to be honest. sorry if its confusing

Thank you Atropus! Although I would have to say that nothing points to that particular pattern here...

Given was 5, 6(+1), 8(+2), 9(+1)...

Why would you not come to the conclusion that the pattern continues ...9(+1), 11(+2), 12(+1), 14(+2), etc.?

Other than that, I enjoyed this one!

I agree with tonjawithaj - you can't know that the pattern is 1 - 2 - 1 - 3 - 1 .... with just the information given.
Jul 12, 2006

It was a good teaser, but I agree- from the part of the pattern that you gave, you don't come up with your answer. It's impossible to come up with your answer from the information given- although it makes sense after.
You should have gone a little farther with the pattern.
Aug 22, 2006

I have to agree. Not enough information to come up with the second half of the pattern.
Dec 25, 2006

I also agree with the previous. One could also come to the conclusion that the second pattern was, 5,6, skip one, 8,9, skip one, thus getting 11,12. But a nice try!
