Sequence Fidget Spinner

Determine the number of times the spinner rotates 360 degrees during the missing spin among the first fives spins. The [color=#ff0000][b]New Sequence[/b][/color] button will provide a new sequence, and the [color=#00ffff][b]Spin[/b][/color] buttons will reveal the number of times the Spinner rotates 360 degrees during that spin. Use the input bar to determine whether the your missing number is correct.
[size=200][b]Things to consider:[/b][/size]
1) What is the difference between a spin yielding a positive number and a spin yielding a negative number?
2) Why is this applet titled "Sequence Fidget Spinner" rather than having the distinction between arithmetic or geometric sequences?
3) Is it possible to create a function that models the given sequence of spins for the spinner?
