Show a number on the LED screen! One digit will display at a time, scrolling from left to right.
Make lucky number 7 display on the screen!
```
basic.showNumber(7, 150)

But we also should pause before showing another number.
```
basic.showNumber(7, 150)
basic.pause(500) // ***

basic.showNumber(7, 150)
basic.pause(500)
basic.showNumber(14, 150) // ***

Keep displaying multiples of 7 such as 21 and 28, but don't forget to add pauses between the numbers!
