it is less then 40 it is greater then 50 it is very hard it is a odd number.?

Is it bigger than a breadbox?

if the difference is 96 Lower number = 245-96 = 149\nbut it cannot be >= 245\n\nso Lower number is between 149 to 245 both exclusive

well we know the 3 space must be even, in order to avoid the last space resulting in another 5\n\nhmmm... i'l work on it, provided you're working as well!\n\n..and #3 mustn't be 0, to avoid another 0\n..lol i'd have had it if i had been home...i made a program to do it, and then left before i finished/ran it lol\n\nbut that, is of course, the correct asnwer, 396*45=17820\n\nhaha thanx for the challenge!

The above answer is correct, but maybe you want to know how he arrived at it.\n\n40 to 50 is a change of 10.  You take 10 and divide it by the original number, in this case, 40 and get .25 or 25%.\n\nGoing from 50 to 40 is a change of 10/50 or .2 or 20%.

Ah, but it is only 14 if you do math correctly.\n\n;-)

You're picking the wrong numbers. listen carefully, i'll tell you the winning numbers for last week 4-23-26-31-40-51.\nNo just joking, its a good idea to have three of the numbers to be even numbers and three to be odd numbers, these hit almost all the time, other than that it's all luck.

Are you into base system 80? (since you constraint was final 10 digit number.) \nThen it is 80^10.\n\nIf you presume that number 10-80 to be counted as a 2 digit number part of the 10 digit then it gets a bit hairy.

I'm not sure I understand your question - do you mean adding odd numbers only to odd numbers and even numbers only to even numbers?  For odd I think it would be the numbers that end in (3 and 7) (1 and 9) and (5 and 5) where they add up to 50, and for the evens the numbers ending in (2 and 8) (4 and 6) that add up to 50.

Because the exponet of both is an even number which is 2\n\nIf you divide by 8 you might get a .5 result.

Well the answer would be about 42.  Wait, no.  Yeah thats right, 42.

8\ntake away o from top and you're left with o on bottom - half - nothing\nor i guess 10 could work, too (or any double digit ending in 0) take away the first number and you're left with 0

4 is the answer. Here's how:\n4 appears after a break of two numbers, so the number that follows 40 must be 4

For the number to be odd, the second digit must be 1, 3, or 5. Therefore, there are three choices for the second digit. The first digit can be any of the six digits, but it cannot be the digit used for the second digit. Therefore, there are 6 - 1 = 5 choices for the first digit.\n\nSo, 5 * 3 = 15.\n\nTo verify, the numbers are: E = 13, 15, 21, 23, 25, 31, 35, 41, 43, 45, 51, 53, 61, 63, 65. So, N(E) = 15 and the solution is correct.

its simple ... 80*70*60 ... 10*0 = 0 !!\n\nright isnt it ??? :D

Each answer is 4 more than the sum of the previous two terms.  The 49 is a misprint and should be 59.\n\n(5+11) + 4 = 20\n(11+20) + 4 = 35\n(20+35) + 4 = 59\n\nso,\n\n(35+59) + 4 = 98\n(59+98) + 4 = 161

do you mean 18 times the sq rt of 50, that would be 127.3\nthen subtract 21 times sq rt 40 divided by 3 times sq rt 2\nOr, is all of the subtraction part above the line\nSee if you can rewrite the problem
