What is the common ratio of this sequence?
{0.5, -1, 2, -4, 8... }

its kind of blurry. can you put a clearer pic?

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
