With the exception of the last 2 terms, this looks like a geometric sequence with a ratio, or r value of 1/2.

The formula for the sum of a decreasing geometric sequence is the first term (a1) / (1 - r). This would give you
(1/3)/ (1 - 1/2) or 2/3.

if its a series you can see that the bottom numbers double . if in mathematical terms, the fraction is decreasing by multiplies of 2.

half of 1/3 is 1/6 and half of 1/6 is 1/12 and so on. then after 1/48 it doubles the top number to 2 so half of 96 really means multiple 96 by 2 because that seems to make sense and you should have. 2/196. hopefully I helped.



o and if its a math problem like a series of adding and such. the person above me has the formula and her answer should help out well.
good luck!

If the top of the fractions hadn't changed to 2 beginning with 2/96, the total would have been (1/3)/[1 - 1/2] = 2/3. You don't show enough of the series to know if the top changes again, how soon, or to what.

Use an advanced calculator. The "/" means you have to divide so like the first one...divide 1 by 3. Just keep dividing all of them and then add them up and you'll get your answer, and if you have an advanced calculator you might be able to convert the answer from numbers to fractions or you can just add up the problem using tools from an advanced calculator.

The equation must be 357 = one hundred fifty + 0.23x the place x is the variety of miles because of the fact there's a value of $one hundred fifty, plus 0.23 consistent with mile. to sparkling up: Subtract one hundred fifty from the two aspects of the equation to do away with the one hundred fifty. 207 = 0.23x Divide the two aspects by way of 0.23 to get x on my own 900 = x so which you will holiday 900 miles. desire this facilitates!
