what pattern would you use when counting quarters?
604893
seperate them into 4s then count them as 1 dollar
743455
one fourth (or one quarter), three sevenths, one tenth, five nineteenths, one one hundredth, four one thousandths (or one two-hundred and fiftieth if you simplify) ;)

a quarter and a nickel because if one of them is not a nickel then try the other. Hah ha!!

Here's the pattern:\nhttp://knitty.com/ISSUEfall05/PATTbits.html

You can get a rough but quick estimate by halving the time, calculating the sum+interest and dividing the result by number of quarters. That is x(1+10*0.076)*80=2000000\nor, x= 14200 (approx)

It helps to put them in order: 1, 1, 1, 2, 5, 5, 7, 8\nThen count in from the outsides to the middle, and it's halfway between 2 and 5, which is 3.5

5/16 is half of 5/8. A measuring tape is the same as a ruler. If it has 1/16" increments, you can count to where you're measuring until you get used to the layout. Avoid the tapes that have 1/32" increments and also those that put centimeters on the bottom. Too much confusion for a beginner.

You use sampling if they are fairly well spread out. Count just 1/4th the area of your sample and multiply by 4. So if you are looking at a 1" square sample you just count what's in a 1/4" square grid.

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...

I would guess 1220, that's the only pattern in the small sequence you gave

26.  The pattern has to start 1, 2, 4, 8, 15.  I see the differences are 1, 2, 4, 7, and the differences of the differences are 1, 2, 3.  The next difference of the difference has to be 4, so, working my way back up, I figure the next difference has to be 11, making the next number 26.

With a calculator. If you're trying to do it in your head, then it depends on how your head works. For me I multiply parts of the numbers and add them. If I'm trying to do something like 15X22 I'll multiply 10X22 and add it to 5X22. For me it's easier to break it down into easier equations.
