Markdown: continue numbered list

Use four spaces to indent content between bullet points

1. item 1
2. item 2

    ```
    Code block
    ```
3. item 3

Produces:

1. item 1

2. item 2

3. item 3

As an extension to existing answers. For those trying to continue a numbered list after something other than a code block. For example a second paragraph. Just indent the second paragraph by at least 1 space.

Markdown:

1. one
2. two

 three
3. four

Output:

1. one

2. two

   three

3. four
