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?
200?
300
100
driftwood
What’s the difference between an apple?

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.

I think I hear u. But Why do it the longer way when you can do it my way?
this question sounds like it came off the LSATs
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…
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…
Really? LAB, you know streekgeek in real life? My goodness, what a privleged young man you are:)
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.
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…
Lab
Maybe farrock is wrong because as you said you must keep the pattern in which case we are back to 300?
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.
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.
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.
