Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:

As you can see, x increases in steps of 1 units. So let's check the difference in y:

So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:

Then:

Finally, the equation of the line is:

Answer:
1/216 and 1/6 raised to the 3 power.
The expanded form would be 100.000 +20.000+0.000+.500+.070+.001
Given that

and

, if

is an arithmetic sequence, then the common difference between successive terms is

.
You then have




So the explicit formula for the

th term is
