If you have to walk a given distance and every two steps, you take one step backwards, how many more steps will you have to take?
I.e. If it would normally take you 100 steps, how many steps will it take you now?November 12, 2013 10:53 pm at 10:53 pm #987458

What’s the difference between an apple?November 13, 2013 1:40 pm at 1:40 pm #987463
jewishfeminist02 – Closest answer. The real answer would be a 200% increase, minus two steps. Instead of 100 steps, you’d have to take 298 steps.November 13, 2013 5:38 pm at 5:38 pm #987464
I think i’m right. My cheshbon is for every 2 steps there’s actually 4 steps because one back and one forward to get back to where you were so technically to get to that 100 steps it would be 2x the amount of steps. Prove to me that Im wrong.November 13, 2013 5:48 pm at 5:48 pm #987465
WIY – you’re looking at it as a four-step sequence, in which case you’d be right. Since every two steps require another step, it is in fact a three-step sequence. Therefore (F – forward; B – backward):
So every three steps advance you the distance of one step.

I think I hear u. But Why do it the longer way when you can do it my way?November 13, 2013 6:43 pm at 6:43 pm #987467pixelateMember
this question sounds like it came off the LSATsNovember 13, 2013 6:48 pm at 6:48 pm #987468
LOL pixelate. I was just thinking that. If it’s too easy to figure out, chances are you’re doing it wrong. Joe Bloggs rule #1 for those in the know…November 13, 2013 11:34 pm at 11:34 pm #987469
WIY – It’s not an opinion thing. It is a clearly recognizable three-step pattern. You could ask better: Why do it the longer way when you can just not take backwards steps?
pixelate & streekgeek – It’s not, I made it up.November 14, 2013 12:14 am at 12:14 am #987470
Well then LAB, I suggest you apply to the College Board. I’ve always wondered what type of people make up those last few math questions. Now I know…November 14, 2013 2:21 am at 2:21 am #987471
Right, because you know me.November 14, 2013 2:34 am at 2:34 am #987472the-art-of-moiParticipant
Really? LAB, you know streekgeek in real life? My goodness, what a privleged young man you are:)November 14, 2013 3:07 am at 3:07 am #987473farrockgrandmaParticipant
Total 296 steps. After repeating the pattern 98 times, for 294 steps, you are two steps from the end. You then take two steps forward, and done. No need to take another step back.November 14, 2013 2:28 pm at 2:28 pm #987474
TAOM – No need to take everything so literally. I don’t know anyone here in real life thank G-d, cuz if I did I wouldn’t be here.
LAB – One request: Next time you post something like that, could you wait like 24 hours before saying the answer so I could actually use my brain? By the time I saw this thread the answer was up already… But at least I get to figure out who is right, you or farrockgrandma. I’m gonna work on it but it’s too early now…November 14, 2013 5:23 pm at 5:23 pm #987475
Sorry about that, streekgeek. And I think farrockgrandma is indeed right!November 16, 2013 12:09 pm at 12:09 pm #987476no longer need seminaryMemberNovember 17, 2013 12:00 am at 12:00 am #987477
Maybe farrock is wrong because as you said you must keep the pattern in which case we are back to 300?November 17, 2013 1:48 am at 1:48 am #987478
WIY – That would depend on whether every two steps require one backwards, or only if you want to advance more steps afterwards – as a prerequisite. I would assume the second makes more sense.November 17, 2013 3:49 am at 3:49 am #987479SanityIsOverratedParticipant
I want to examine this question from a different angle.
What kind of person would take a step backward for every 2 steps already taken?
Perhaps we’re talking about a child, in which case the math will anyways get confused somewhere between 11-90.
Or maybe this is a severe case of OCD. I would recommend immediate hospitalization instead of trying to count his/her steps.
There’s also the chance this question has ADD/ADHD roots. Here we will never really find an answer, because they sold out in the bookstore.
All in all, I think this question needs to be rephrased to something more practical, so philosophers like me don’t notice it.November 17, 2013 4:25 am at 4:25 am #987480live rightMember
the driftwood is not coming any closer to the shore. its like a tease. you think its coming closer but then its suddenly far back and out of reach. you can calculate how many waves it rides, and how many waves it has yet to ride, but it will still remain out of reach when the tide comes in to drag it back out once more.November 18, 2013 3:25 am at 3:25 am #987481SanityIsOverratedParticipant
I do like this analogy better. It’s a great question for someone stranded on an island, or someone bored enough to care. At the moment I am neither, so good day to you all.
