From 1-100, it appears 20 times, in 19 different numbers.5152535455051525354555657585965758595For every interval of one hundred after that (101-200, 201-300, etc.) except for 500, it will be the same amount of fives. So, 20 instances times 9 different intervals (still excluding 500-599), there are 180 fives.Now we'll consider 500-599. From 0-99, there are 100 numbers, so there are also 100 numbers from 500-599. That means there is an extra 100 fives, for each 5 in the hundreds place. Add that to the original 20 from the tens and ones place, and there are 120 fives between 500-599.When we add that 120 on the our other 180, we arrive at the grand total of 300 fives between 1-1000.
Sum from 1 to n of (2n-1) = n2 (2*500-1)=999 (500)2=250,000
The sum of the first 500 counting numbers (1-500) is 125,001.

There is no limitation given to the number of digits in the number, thus: For 3 digit numbers: to be less than 500 the first digit can be only one of {1, 2, 3, 4} leading to 4 × 5 × 4 = 80 numbers For 2 digit numbers: they are all less than 500, and there are 6 × 5 = 30 numbers For 1 digit numbers: they are all less than 500, and there are 6 numbers Thus there are in total 80 + 30 + 6 = 116 numbers that can be made form the digits {1, 2, 3, 4, 5 ,6} without repetitions that are less than 500.
