Answer:

Step-by-step explanation:

Answer:
The explicit formula is : 
Step-by-step explanation:
Here, in the given GP sequence,
a(4) = 12, r = 2
Now, the general term in a geometric sequence is given as:

Now, here substituting the value of n = 4 , we get:

So, here the first term (a) in the sequence = 1.5
So, the explicit formula is given as :

Hence, the explicit formula is : 
Answer:
(0,-0)
Step-by-step explanation:
P(0,0)=P(0,-0)
