See attached graph.
The y-intercept is (0, 1), since the line is at that point when it intersects with the y-axis.
The common ratio is 1/4, since the y value multiplies by 1/4 for each unit on the x-axis.
The difference starts off by 7. Then it continues to double. Then the answer is 14, 28, 42. The answer doubles every time.
0.8 - 0.05 = 0.75
0.75 is the answer.
or 3/4ths
We use the law of the sum of the 3 first terms of the geometric sequence:
