Using a graphing utility, we can graph the first 10 terms of the sequence by plugging in n=1,2,3,...,10 into the formula for a(n). The graph should have the y-axis labeled "a(n)" and the x-axis labeled "n". The graph should show that the sequence starts at a(1) = 11.6 and decreases linearly to a(10) = 7.6, where the slope of the line is -0.4. The best choice is C because it matches this pattern, with the sequence starting at 11.6 and decreasing linearly to 7.6. The other choices do not match this pattern or do not have the correct range of values for the sequence.
