I am fairly sure the only possible values are 34 and 38 ..........
From observations made on small series' of 1 to 2n, the amount remaining on the paper after the numbers are crossed out is equal to (1 + 2+ .... +n ) + kn where k is any integer between 0 and n. ( this formula is not too hard to find, but would take a while to explain) The sum of the numbers 1 to n is ½ (n2 +n). ( this can be proven by adding up pairs of numbers, starting from the outside of the series and going in, e.g. if n= 100, you add up (100 +1) + (99 +2) + (98 +3).......) Therefore: ½ (n2 + n) +nk = 1615 So: (n2 + n) + 2nk = 3230 And: n + 1 + 2k = 3230/n As we want an integer value for n + 1 + k, we look at the factors of 3230. 3230 = 2 x 5 x 17 x 19 n must be a combination of these factors There are many combinations of these factors , but some e.g. 2 are going to be way off. Instead of using tonnes of trial and error, lets find a range. Min value: if n is low, k is high, therefore min value for n would occur when k is n. Subbing in values, we get 3n2 + n - 3230 = 0 using a quadratics function on graphics calculator (if you dont have one, go look up the quadratic formula) this equals approx 32.6 max value for n would have k = 0 n2 + n = 3230 = 56.33 approx. Combining the factors the values found within this range are: 34 (2x17), 38 (2x19) If n = 34 34 + 1 + 2k = 3230/34 2k = 95-35 2k= 60 k = 30 this means it works as k is less than n and is an integer. If n= 38 38 +1 +2k = 3230/38 2k = 85 - 39 2k =46 k= 23
i hope this is right - Cat : )
what is the ratio of the numbers vowels to the number of consonants in the english alphabet
It is common in the Vietnamese culture to have lucky numbers. Also, in Vietnam there are so many Pho restaurants that people remember them for their numbers, instead of a long title as a name. This idea simply migrated along to the US as they began opening here.
In association football, the first advent of players wearing numbered shirts came on 25 August 1928, when Arsenal and Chelsea wore numbered shirts in their matches against The Wednesday (renamed Sheffield Wednesday soon after) and Swansea Town, respectively. After a number of experiments with the system - which met with opposition on the basis that numbers on shirts would "spoil club colours", it was decided to make them a permanent feature in 1939. http://en.wikipedia.org/wiki/Squad_number#First_use_of_numbers
Serial numbers in the documents give a better control over missing of documents. however, if the numbers are pre-printed it gives more control than manually numbered documents. further, it provide the assurance on the completeness of the transactions or what ever you concern.
At the time of the US Civil War, very often troops numbers were not always an exact number. One reason for this was on the Confederate side, at least, their record keeping was not always accurate. The Union's troop numbers are deemed by historians to have much better accuracy. Also, very often the number of casualties and battle deaths were also not easy to account for. Wounded soldiers who later died, often were not so easy to track.With all that said, the round numbers of troops involved in the Second Battle of Bull Run were as follows: A. Union forces under General John Pope numbered 70,000; and B. Confederate forces under General Robert E. Lee numbered 55,000.
64 and 65
First, take 137 ÷ 2 and you get 68.5. 68.5 is the average. What two numbers average 68.5, 68 and 69. The same two numbers equal 137.
You do not specify the serial numbers, signatories or quantity. The last Australian One Dollar notes were put into circulation in 1982, and were progressively withdrawn from circulation from 1984 after the introduction of the One Dollar coin. Because they have consecutively numbered serial numbers, they are presumably in mint uncirculated condition. A quantity of consecutively numbered uncirculated banknotes in mint condition, depending on the serial numbers, could fetch anything from $7 to $925 AUD each. As a "range" of banknotes, they potentially have a higher value than might be expected for the single note value multiplied by the number of notes. A reputable coin dealer will be able to give a more accurate valuation.
The numbers are 65 and 66.
I would presume the way they are numbered everywhere else. Most of them are consecutively numbered. Some are odd numbers on one side, even numbered on the other side. Some are not in strict numerical order at all. My address is 642, but the neighbor on my left is not 640, it is 636, Two houses down from that the address is 624. I don't know why, it just is. Check with the municipality where you live or are inquiring about to find out.
The numbers are 76 and 77.

they are numbered by their Atomic numbers
An Australian 2001 Five Dollar note (MacFarlane/Evans)(serial DK01826180), uncirculated and in absolute mint condition could fetch up to $33 AUD. If it has been circulated but still in good condition, it might fetch anything from $6 to $14 AUD. A consecutively numbered wad would have a signifcantly higher value. A reputable coin dealer will be able to give a more accurate valuation.
The sum of the first 70 consecutive odd numbers is 4,900.
