Answer:
Slope = 3
Step-by-step explanation:
For a proportional relationship, the slope of the line is simply y/x.
So using any given pair of values from the table, say (1, 3), the slope is:
y/x = 3/1
Slope = 3
Given:
The sequence is:

To find:
The 6th term of the given sequence.
Solution:
We have,

Here, the first term is:

The ratio between consecutive terms are:


The given sequence has a common ratio 5. So, the given sequence is a geometric sequence.
The nth term of a geometric sequence is:

Where, a is the first term and r is the common ratio.
Substitute
to get the 6th term.




Therefore, the 6th term of the given sequence is 50000.
Error: They subtracted 9x from both sides when they should have subtracted 12. You can’t subtract unlike terms
Correct: x=-5/16
Subtract 12 from both sides to get -5 on the left and add 7x and 9x to get 16x. Divide both sides by 16 to isolate x.
