Thanks, but why?

Don't question the collective. And give us your little brothers lunch money... punk!

Why is it that I can solve Caluculus problems but I can't do 6th grade math?

Cuz it's not math? I hate stupid puzzles. Give me a nice ODE any day.

A 0,3,6,8,9 __

3+3=6, 6+2=8, 8+1=9 pattern is add 3,2,1. so 9+3=12, 12+2=14, 14+1=15

B 1,4,7,11,14 __

Pattern here is looking at the numerals, 1,4,7. add 10 to each for 11, 14, 17

C 2,5,10,12,13 __

Because 17 is the only choice left.

I feel so stupid. Topology is easier than this.

NoHills, I may be retarded, but in your answer for A (15), the number 15 isn't the next in the sequence... it would be the third additional number in the sequence (after 12 and 14). B makes sense, but not C.

**snow_slider** · 05-04-2006, 10:14 AM

I may be wrong, but I read the question as which letter does the number combination 15, 16, 17 belong to. I'd say B. because 15, 16, 17 is odd even, odd, and that's the sequence in B.

It doesn't have to be the NEXT number in the sequence, just which group it belongs in. Reading comprehension is usually part of these questions....

**smmokan** · 05-04-2006, 11:01 AM

I'm pretty sure they mean the next number, or as slider said above, the next three numbers in the sequence- not just any number in the following sequence.

**Cyber Cop** · 05-04-2006, 11:20 AM

I can see why the US ranks so high in math.

**Nohillsnearby** · 05-04-2006, 11:46 AM

Nevermind. Thanks Tipp!

**Tippster** · 05-04-2006, 11:48 AM

"To which group do the numbers 15,16, and 17 belong?" does NOT imply it's the next number in the sequence. I do agree with Snowslider, tho.

But RatherBskiing didn't say my answers were wrong, that they needed to be grouped together as an answer for one letter.

**Cyber Cop** · 05-04-2006, 11:53 AM

B 1,4,7,11,14 __

except the sequence is not odd even odd.....7,11

unless my dislexia is kicking in.

**mtnbikerskierchick** · 05-04-2006, 11:56 AM

I took it to the math teachers here in my high school and they have no idea.

**Cyber Cop** · 05-04-2006, 11:58 AM

the sequence is either even,odd,eeven,even,odd or vice versa. two odds and one even fits.

Stuff like this is why I told my math teacher in high school that I didn't want to take calculus -- that I'd never ever use this in real life after school. She made me take calc anyway... which I have completely forgotten.

My answer to this question: "Which group do you think each should belong to?"

**yentna** · 05-04-2006, 12:17 PM

I've always been okay at math but didn't like it - problems like these are annoying. Although, they do make your brain look at different angles, challenge you to think outside the box and all that. Maybe not so pointless.

Anyway, I didn't get a right answer, when do we find out the teacher's answer?

The difference is calculus has numerous real-world applications. This kind of puzzle does not.

Pattern finding doesn't have real world applications?

**GoldMember** · 05-04-2006, 12:31 PM

Okay, I'll try:

A 0,3,6,8,9,16
B 1,4,7,11,14,17
C 2,5,10,12,13,15

The difference between each of the numbers goes like this:

3 3 2 1 7
3 3 4 3 3
3 5 2 1 3

All the differences are prime numbers except the 4 which ends up in the middle of the pattern. It's the only thing I can come up with.
