By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is
Sequence is collection of numbers with some pattern .
Given sequence
We can see that
and
Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2
Now term of this Geometric progression can be written as
So summation of 15 terms can be written as

Given:
The table of values.
Hours (h) Dollars (d)
1 42
2 84
3 126
4 168
5 ?
To find:
The correct statements about the table.
Solution:
From the given table it is clear that,
This pattern can be defined as
Multiply h by 42 to get d. So, option A is correct.
Using this pattern, we get
The missing value in the last row is 210. So, option D is correct.
From the given table it is clear that the rate of change is $42 per hour because dollar is increasing by 42 in every hour.
A real-world situation that is represented in the table is “Richard is a video game designer and earns $42 per hour.”
Therefore, the option E is correct.
