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:Decay
Step-by-step explanation: because of perenthesis

Answer:
The sum of first five term of GP is 19607.
Step-by-step explanation:
We are given the following in the question:
A geometric progression with 7 as the first term and 7 as the common ration.


Sum of n terms in a geometric progression:

For sum of five terms, we put n= 5, a = 7, r = 7

The sum of first five term of GP is 19607.
Verification:

Thus, the sum is equal to product of 2801 and 7.
