10,23,45,67,89 _____take out if desired [ this line matches the duplicates in bottom lines ]

18,25,30,47,69

16,27,38,49,50 _____v-tracs

14,29,36,58,70

12,34,56,78,90

25 lottery pairs this set. Take out the duplicates from this set that contain even odd digit that appear in the upper set. Will leave 20 lottery pairs of even and odd. Total 45 no match lottery pairs both sets. Add the 10 doubles not present will total all 55 lottery pairs

20,46,13,57,89

40,28,15,39,67

60,48,... [ More ]

you can probably create 5 lines with 2 numbers odd digits 2 numbers even digits and 1 number even odd digits.

13,20,46,57,89

work the other 4 lines from there

the 5 lines

20,46,13,57,89

40,28,15,39,67

60,48,17,59,23

80,26,19,37,45

24,68,35,79,10

five combinations I come up with without duplicating 2 numbers together either ascending or decending from one line to another.

each number contains an even odd digit

16,27,38,49,50 _____v-tracs

Oh you could have won a bunch of stuff from Will Shortz if you sent it in to his program and they picked you.

Thanks for the answer.

Here's another puzzle;

This challenge comes from Ed Pegg Jr., who runs MathPuzzle.com.

Writedown the digits from 2 to 7, in order. Add two mathematical symbols toget an expression equaling 2010. What symbols are these

Cool. Are there any other ways it can be done

Mathematical relationships existed a long time before we figured them out, so those 4 sets of numbers have existed since the very begining of this universe, and perhaps longer if there are (were) other universes. Are you going to start using them for every drawing of every game, or is there something special about the next drawing in one particular game

Thanks, Blackie. That's what he said on the radio this morning, too. I'm thinkikng that's the site you went to.

And considering the sets of numbers;

10,32,54,76,98

18,36,54,72,90

50,61,72,83,94

54,63,72,81,90

are you thinking what I'm thinking here?:

10,32,54,76,98

18,36,54,72,90

50,61,72,83,94

54,63,72,81,90

(I bolded the ones within lottery matrixes)

Hmmm, 10 18, 32, 36, 50, 54....take one of the numbers 10, 18, 32, 36 as the Mega number, o... [ More ]

Here is what it says on the internet:

A: There are four possible sequences of two-digit numbers:

10,32,54,76,98

18,36,54,72,90

50,61,72,83,94

54,63,72,81,90

10 32 54 76 98

If you go about it logically it's actually pretty simple. The first number has to be 10 or more, and the last can't be more than 98. That's a range of 88, so the maximum spacing is 22, and simple trial and error gives the correct answer on the first try. It's also a very elegant answer, since it's each pair of digits in order, but with the individual digits reversed.

Off the top of my head I would say 18-36-54-72-90, unless I don't understand the problem.

This was heard on the Will Shortz Sunday Puzzle segment on NPR this past Sunday morning.

Not exactly lotto, but I was thinking maybe these numbers could be turned into a lotto ticket if they're all within a matrix.

Here's the puzzle:

It comes from Scott Kim, the puzzle maker for Discover Magazine. He hasa 2010 page-a-day calendar just out called Mind Benders andBrainteasers. Here's one of the puzzles in it: Name five two-digitnumbers that are evenly spaced out like 32, 34, 36, 38 and 40... [ More ]
