Do you have a better picture and which question or all of them
Answer:
The general formula for nth term of given sequence is:

Step-by-step explanation:
Given sequence is:
54,18,6.....
In order to write the general formula of a sequence, first of all the common ratio has to be found. Common ratio is the ratio between consecutive terms of a geometric sequence.

The general formula is:

Putting the values of a1 and r

Hence,
The general formula for nth term of given sequence is:

Answer:
x = 1
Step-by-step explanation:
From the table shown in the picture,
For input value x = 1, output values of y = 2, 4, 6, 8, 10
Similarly, from the graph shown,
For input value x = 1, output values of y = 2, 4, 6, 8, 10
Therefore, both will represent the same relationship.
From the graph attached, straight line parallel to y-axis is x = 1.
Therefore, x = 1 will be the correct option.
