A sequence can be generated by using an = an-1 – 7 where a1 = 18 and n is a whole number greater than 1.
What are the first five terms of the sequence?

A. 18, 11, 4, -3, -10
B. -7, -14, - 21, - 28 , -35
C. 18, 25, 32, 39, 46
D. 18, -126, 882, -6,174, 43,218

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
