Hi Guest, you have not done it the lazy way, you have done it the most straight forward (and long) way.

I'll see if I get the same answer...

All the 720 arrangements of the digits 1 through 6 are put in numerical order. What is the 428th term?

How many are between 100 000 and 199 000   That would be 1*5! = 120

200 000 - 299 000    That would also be 1*5! = 120

300 000 - 399 000    That would also be 1*5! = 120

So that is 360 so far    428-360= 68 more...

So it is going to be between 400,000 and 499,999

How many between 410,000 and 419,999

the position of the 4 and the 1 is set so that would be   4! = 24         68-24= 44 more to go

How many between 420,000 and 429,999. Another 24                     44-24=20 more to go

So it is going to be between 430,000 and 439,999

How many between 431,000 and 431,999.     3!=6

How many between 432,000 and 432,999.     3!=6

We canot repeat the 3 or the 4 at the front so

How many between 435,000 and 435,999.     3!=6                             20-18=2 more to go

Next is 436 125, then 436,215

So I think 436,215 is the 428th term.     That is what I get

check

120+120+120+24+24+6+6+6+2 = 428  Seems ok

they are not the same so one of us has made a mistake

Thanks Melody! The reason I said it was " a lazy person's solution" was because I simply wrote a few lines of computer code and it spat them out in seconds!! It also did the counting from the top!! It could very well have a small bug in it as far as counting is concerned. I might go through it and see if I can spot it!!.

Thanks, there could be a 'bug' in my logic too ://
