Answer:
1 : 2
Step-by-step explanation:
Since the quadrilaterals are similar then the ratios of corresponding sides are equal, that is
=
= 
Thus the ratio of perimeters is also 1 : 2
1st let's calculate r the common ratio:
r = (-20)/4 = (100/-20) = -5
Value of nth term = a₁.rⁿ⁻¹, where a₁= 1st term and n, the rank
Value of nth term = 4r⁽⁷⁻¹⁾ = 4.(-5)⁶
Value of nth term = 62,500
