Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)

Answer:
(3r+8)(4+1)
Step-by-step explanation:
We have an equation: 2/1= ?/2.25
Cross multiply:
1*?= 2*2.25
⇒ ?= 2*2.25= 4.5
The final answer is 4.5~
They are congruent because of the angles, which means the congruency reason should be SAS.
