Answer:
Subtraction property of inequality
Step-by-step explanation:
Step 1: Definition of Subtraction property
Subtraction property of equality refers to balancing an equation by using the same mathematical operation (minus) on both sides.
Step 2: Relate the definition above with the given question.
It can be seen from the statements in the question that 3 was subtracted from both sides of the initial equation to get:
For the<span> geometric sequence, it has two forms of formula

<span>We are interested in the recursive formula now
</span>
<span> {-80, 20, -5, ...}
The common ratio is (20/-80)=(-5/20)=-1/4=-0.25
So our r</span><span>ecursive formula would be
