Answer:
Geometric Sequence
Step-by-step explanation:
In this case it is Geometric Sequence as it has a common ratio of 5
Formula for nth term: a(n) = ar∧n-1
so if we take the third term we will calculate as follows:
50 = 2(r)∧3-1
50÷2 = r∧2
√25= r
r=5
are of trapezoid =1/2×height(a+b)
A=1/2×8(10+20)
=4×30
=120cm*
-11/15 is the greatest because ita in negative
