Do you like math puzzles? Here:

[Not Heidi]

I absolutely suck at math, but I need an answer - if anyone can figure it out. I sure as hell can't.

My cardiologist has instructed me to walk two miles per day. I get on a treadmill and set the speed at two miles per hour, and walk for an hour. (That math, I can handle.)

I'd like to know how to get an equal workout on a recumbent bike. I haven't the foggiest idea how to get to the answer.

Do you know how?

1. Walking 2 miles in 2 hours will burn around 220 calories

On average, an individual can burn 210 calories for a moderate intensity 30 minutes ride on a recumbent bike, which can make a great contribution to an overall weight loss goal.

Adjust for your level of intensity on the bike

2. Not really a math question.

Go back and ask the cardiologist how long he wants your heart rate elevated and to what rate. The two miles is not really what you want to solve for.

3. I don't think its math.

it is more of an issue of what the purpose is. If your cardiologist asked you to reach a specific intensity or burn a set number of calories.

You can look at this https://www.healthline.com/health/calories-burned-walking

to give you an idea. at 2miles per hour, look up the first column and you will get an approximate number for your weight.

Then use that

to see the equivalent for a recumbent bike to reach the same intensity.

If he asked instead for a specific heart rate just measure it when exercising and match that on your recumbent bike.

4. I fired my cardiologist. Sticking with my family guy. However, for a math puzzle:

can you fill in the next line?

1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7 8 9
2 4 6 8 1 3 5 7 9

(and on and on until you get to the last line: )

9 9 9 9 9 9 9 9 9



**** It's called a number sequence. My high school Freshman teacher (a local genius) was totally impressed. My competition student for top scholar asked, "What's the PURPOSE of this?!"

5. My high school math teacher would say that such problems were meaningless,

because you could never possibly know what the next sequence was.

The math program I was in was called UICSM, for the University of Illinois Committee on School Mathematics. It was a "new math" in the early 1960s and was incredible. We proved EVERYTHING which was why I recalled lots and lots, and some 35 years after taking my last high school math class was able to test into 2nd year algebra at my local junior college. An absolutely amazing program. Even now, nearly 60 years after high school, I still remember a lot of content from that class.

6. next line is

369369369

9. Correct. So, I take it you can take it to the limit.

7. This one's pretty easy

Each line doubles the numbers of the one above it. If the doubling pestles in a 2-digit number, add the digits. The last column is 9 all the way down because doubling 9 gets you 18, which adds up to 9.

So…

1 2 3 4 5 6 7 8 9
2 4 6 8 1 3 5 7 9
4 8 3 7 2 6 1 5 9
8 7 6 5 4 3 2 1 9
7 5 3 1 8 6 4 2 9
5 1 6 2 7 3 8 4 9
1 2 3 4 5 6 7 8 9

8. Yours works fine, not my formula, I had no idea different formulae existed.

Each line of both of ours has its own pattern - that is, the same line patterns for both of ours probably in different line orders (I haven't played yours all out.

I take it your last line is all 9s like mine.

So, wow, I guess different formulae could happen - say, multiples of 3, 4, whatever. Mine is not a multiple. I haven't given my formula.

But not to claim "genius" for me, but I "discovered" mine without any prompting or clue from anybody or any book at the age of 14 (late?). Just played.


And there and then conceived special mental capacity if not "genius". I guess I'll have to revise 60 years of self-concept!

10. I wouldn't exactly call mine a "formula"

Military Intelligence personnel are big on pattern recognition. I just noticed that every number in the third line is twice as large as the one above it, and went from there. Calling “2 plus 2” a formula is an insult to real formulas.

I really tried to get to all 9s but I did thirty rows, and the “123456789” thing came up several times. So…I assumed that was the last row in the series.

11. Thanks for another blow!1 You might have just left it at "pattern recognition" - haha!1
