I agree July 25th.  The five stays the same, but the first numbers starts at 2, declines to zero and then starts back toward 2

this one is pretty easy\nafter 46 i will give u the next no.\n\n54,55,62,63,69,70,75,76\n\nc it goes like that 80,81,84,85,....

Find d?\n\nWhere are a, b, and c?\n\nwhy don't you write out the entire problem if you want help?

Could be 10,14,13. The odd terms differ by 3 (eg. 4-1,7-4), the even terms differ by 4.

111221, 312211, 13112221, 1113213211, ...\nOR\n1231, 131221, 132231, 232221, 134211, ...\nOR\n3112, 211213, 312213, 212223, 114213, ...\n\nEach is based on the digit makeup of the previous term, but I need one more term in the sequence to be sure of the rule.

Let x be one number\nother number=100+x\nproduct\n=x[100+x]\n=100x+x^2\ndifferentiating\nf'x=100+2x\nthis is a minimum \nwe put this=0\n100+2x=0\nx=-50\nthe numbers are\n50,-50

One needs to ask the question........how many times will this number 3 be divided into this number 6? Or how many times can six be divided by 3.  Take a candy bar that has 6 parts and divide it equally between 6 children, each child will receive two pieces. Check would be 2 x 3 = 6 Be sure to work the division problem showing the answer, number multiplied, subtracted.......in otherwords show the entire problems steps

This is more of a word problem or a riddle than a math problem.\n\nThe answer is 7 (SEVEN).  Remove its first letter and it becomes EVEN!

grab a calculator and try 1.1 x = = = = =  until you get a number >2.\nthe first time you hit = is ^2, next is ^3 etc.  count.\n\nN=7

Look at them carefully, find out the diff between each number and it should be obvious.\n\nEquations?

I don't know the rule... I don't even think there is one you jsut divide the fraction and see if it repeats... But to change a decimal into a fraction (if you can round the fraction to the hundreths-the first 2 numbers after the decimal-) but multiply the decimal by onehundred and then try to reduce...

add the numbers\n15\n19\n42\n19\nnext number equals 15..... and each has a 2 and a 7 in it\n\ntry 2742 sounds like a good answer for neopets lenny conundrum answer possibility but not fully sure..... lucidlyinsane

If it is an arithmetic sequence, then the number between should be exactly half way.\n\n214 and 225 are 11 apart, so you want to pick the number that is 5½ higher or lower (namely 219½).  The pattern should follow for all numbers earlier or later.\n\nSo the answer is:\n...208½, 214, 219½, 225, 230½...

The next number is 6 (and every subsequent number is 6 as well).\n\nIt has to do with converting bases.  If you have a_n=6, then n has to be greater than or equal to 2.  Therefore, \n\n6 in base 2 = 110\n6 in base 3 = 20\n6 in base 4 = 12\n6 in base 5 = 11\n6 in base 6 = 10\n6 in base 7 = 6\n\nand so on....\n\nHope that helps!

Each digit is even\nEach digit is different\nThe number has 4 digits\nIt is divisible by 4.\nIt is not divisible by 8.\nIt is a square.\n\nYour answer must be: 6084\nIt is the square of 78.\nAll digits are even and different.\nIt is divisible by 4.\nIt is not divisible by 8

Figure it out - when you divide 60 by each of those numbers, which one leaves a remainder?
