Answer is the second one. an= -0.5n2-n+9
Can please send a bigger pic if you really want someone to solve that problem
You haven't shared the instructions; please do so now.
If you're supposed to find x that satisfies this equation, this is a relatively challenging problem.
One way to approximate the solution would be to plot y = (3/2)x + 7/2 and y=2^x carefully on the same set of axes. Try to read off the x- and y-values at the single point where these two graphs intersect. (x, y) would be your solution.
I did this graphically on my calculator and found that the point of intersection is (3,8).
To check, determine whether y = 2^x is true when x = 3 and y = 8, and also check whether y = (3/2)x + 7/2 is true for the same x and y values.
The probability of not winning will probably be 0.1
