The positive five-digit integers that use each of the digits 1, 2, 3, 4 and 5 exactly once are ordered from least to greatest. What is the integer in the list?
#2
+1
5! = 120 possible 5-digit numbers
The average value of each digit is =1+3+4+5+9=22/5=4.4
4.4 x 10,000th place x 120 permutations of 5 numbers=5,280,000 +528,000+52,800 + 5,280 +528 =5,866,608
Which is the same as multiplying: 528 x 11,111 =5,866,608.
Your question dosn't make sense as written ! What do you mean by " What is the integer in the list"?
12345 is one integer that goes from "least to greatest" !!
In my answer here, I also see that "What is the integer in the list?" doesn't make sense. I asked the asker (confusing) to clarify this mishap.
