Best ResponseYou've already chosen the best response.1You're adding up 5 numbers. The first of which is 600. How did they then add up to 116.5? :o That's even smaller than the first number that you're adding... You silly billy _

Best ResponseYou've already chosen the best response.1\[\large\rm S_n=a_1\frac{1r^n}{1r}\]So you determined that your common ratio, \(\large\rm r\), is 1/2 since you're dividing by 2 each time. So we'll plug in all of the information, \[\large\rm S_5=600\cdot \frac{1\left(\frac{1}{2}\right)^5}{1\frac{1}{2}}\]

Best ResponseYou've already chosen the best response.1If you want to punch it all in at once, I would try something like this,\[\large\rm 600*((1.5\wedge5)\div(1.5))\]Otherwise, if you like to do it piece by piece, that's fine also :)
