Coding challenges for lucky 7.

Before we get started

Complete the lucky 7 activity and your code will look like this:

basic.showNumber(7)

Challenge 1

But we also should pause before showing another number. Let's add a pause of 500 milliseconds.

basic.showNumber(7)
basic.pause(500)

Challenge 2

@video td/videos/lucky-7-1-2

What about other multiples of 7? Let's display the next multiple of 7 on the screen!

basic.showNumber(7)
basic.pause(500)
basic.showNumber(14)

• Run the code to see if it works as expected.

Challenge 3

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