how come some numbers do not follow the same number convention as the rest of the teens like ,17,19?

I think It has something to do with the Significance of the the number twelve to romans. \n12 months\n12 titans\n12 apostles\nso the numbers 1- 12 are unique sounding although we use a base 10 arabic system for the numerals\nthirteen and fifteen are simply changed for ease of use, but they do use the 'teen' system. \nI think they are changed because the 'e' sound in three is too similar to the 't' in teen, and the transition from 'v' to t in fiveteen would be foriegn sounding. \nLike why we pronounce the suffix -ed differently for words ending with different sounds. Eg. worked, stopped, 'ed' is pronounced 't'. milled,jelled 'ed' is pronounced 'd' and sometimed 'ed' is pronounce 'ed' shredded, etc. \n\nSo the numbers up to twelve are unique, but only in roman based counting systems.\n\nJessom made a good point though.\nWhy don't the teens follow other number conventions like twenty, thirty, forty,

Thirteen may be considered a "bad" number simply because it is one more than 12, which is a popularly used number in many cultures (possibly due to it being a highly composite number).

Why 18?  Why not 17, 19, or 278?  If you want that kind of info, I suggest Google.  I guarantee you that you will find info on numerous haz mats.

the words for the numbers 1 through 19 are among the oldest words in the language. The rules for numeration had not been made when the words were invented. You will find that in most languages at least the lower "teen" numbers, 11, 12, 13, 14 and even 15 have special words to describe them. Some languages have special words for up to 20. This is because in earlier times, counting only went up to a certain number and after that, the amount was considered "many" or "countless." It didn't matter much if there were 45 deer or 62 to hunt, because just one would feed the tribe that night. But it might matter if there were 7 lions or 14 to avoid, so those numbers were invented.\nThese examples I just made up; they aren't definitive, but I think you can see how they may illustrate what probably happened.

Hmm, I hope the reason is not because 4 is IV and 6 is VI in roman numerals. If so, I can't finish the proof by explaining why someone would perceive IV and VI as the same number :)

there are different reasons. 3 is a very powerful number in a lot of cultures. also, in fairy tales they like to isolate people, things, etc. having thins come in 3s allow them to create a patten, and then have the third person or thing break this pattern.

As there is 22 elements in first call,\nOur first is 0\nmiddle is 11\nend is 21\nNow 11th element is 35 which is less than 37.\nSo now our first is changed to 12\nand middle is 17\nend is 21.\n17th element is 42 which is greater than 37\nSo now we will chage end to 16.\nfirst is 12 and middle is 14.\n14th element is 42>37\nSo we change end to 13, first is 12 and middle is 13.\nNow 13th element is 37. So we will now reurn 13.

22/8 isn't any more round than 22/7 if you're talking about rounding to the nearest whole number. They're just different numbers.\n\nAlso, 22/7 is bigger so it's not being rounded up.

Today's youth don't have a monopoly on confusion, but at least they have the excuse of lack of experience, where older folks just seem to wallow in confusion (perhaps for attention lol).\n\nThe youth of today will figure things out, and for the most part seem to have a pretty good grasp on things.

The number is too small for a real "pattern" to emerge.\nThe digits could be the first 10 values of some sequence given by some ( many ) recurrence relation, could be ...\n\nIn order for a proper pattern to emerge, it should be much larger...

I do both of those and I also test numbers for divisibility.  My car license plate has as its numeric part the number 594 which is divisible by 11, that's how I remember my license plate number.  Also, when someone asks me to pick a number between 1 and 10, I usually pick pi, phi, or e, just to be a smart@$$.  They didn't say an INTEGER between 1 and 10, did they???

According to Chaos theory there are some numbers (such as Pi) which will never repeat no matter how far down you take them.  Therefore the current theory is that there is no last digit of Pi.\n\nFor more information try reading up on Strange Attractors in mathematical formula.

actually the way i see it there are two numbers in the space.\nThe difference between each number is a prime number(consecutive prime numbers)\ndifference between 1 and 3 is 2\ndifference between 3 and 6 is 3\ndifference between 6 and 11 is 5\ndifference between 11 and the next no. is 7 i.e 18\ndifference between 18 and next no. is 11 i.e. 29\ndifference between 29 and 42 is 13\ngot it?\nhope your question was wrong.. hehe\n\nWhat i'm trying to say is the two numbers are\n18 and 29

The "powers" often assigned to numbers come from old superstitions and folklore. \n\nThirteen is supposedly unlucky because there are thirteen witches in a coven, Judas was the thirteenth Apostle, etc.\n\nSeven is supposedly lucky because it appears frequently in the Bible, seven heavens, seven seals, etc.

Actually, there are more numbers that do not repeat than numbers that repeat. \n\nAnd pi is one of those numbers that does not repeat.

You can put it as the last number, right after 2, because that would be the 13th number.\nOr it could be after the number 6. If you add all the numbers and divide by 13, you would get 6.
