Supplementary is 180 so 180 times 3
<h3>
Answer:</h3>
- a_n = -3a_(n-1); a_1 = 2
- a_n = 2·(-3)^(n-1)
<h3>
Step-by-step explanation:</h3>
A) The problem statement tells you it is a geometric sequence, so you know each term is some multiple of the one before. The first terms of the sequence are given, so you know the first term. The common ratio (the multiplier of interest) is the ratio of the second term to the first (or any term to the one before), -6/2 = -3.
So, the recursive definition is ...
... a_1 = 2
... a_n = -3·a_(n-1)
B) The explicit formula is, in general, ...
... a_n = a_1 · r^(n -1)
where r is the common ratio and a_1 is the first term. Filling in the known values, this is ...
... a_n = 2·(-3)^(n-1)

Hello! remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any Table, so I've chosen an exponential function that follows this rule:
Some x and y-values are given in the following table:
Let's take the average rate of change from x = 5 to x = 8:

Answer:
1) x+y=-2
x=-2-y
2) x-y=-8
substitude value of x
(-2-y)-y=-8
-2-2y=-8
-2y=-6
y=3
Substitute value of y in 1
x=-2-3
x=-5

the correct question in the attached figure
Let
s----------> total savings
case a) Israel added $80 to his savings
we know that
80=(1/8)*s-------> multiply by 8 both sides------> s=$640
the answer case a) is
the equation is
80=(1/8)*s
case b) Israel added $120 to his savings
we know that
120=(1/8)*s-------> multiply by 8 both sides------> s=$960
the answer case b) is
the equation is
120=(1/8)*s
