Answer:
The required recursive formula is:

Step-by-step explanation:
We are given a geometric sequence as:
6,-18,54,-162,.....
Clearly after looking at different terms of the sequence we could observe that the sequence is an geometric progression (G.P.) with common ratio= -3 denoted by r.
Let
represents the nth term of the sequence.
This means that:

As the common ratio is -3.
so,

Hence, the required recursive formula for the geometric sequence is:

Answer:
<h2>A: -12</h2>
Step-by-step explanation:
Put the values of a = -46 and b = 34 to the expression a + b:
-46 + 34 <em>use the commutative property a + b = b + a</em>
= 34 + (-46) = 34 - 46 = -12
