Evenly increasing 2x2rib

Hi, trying to increase bottom up sleeves in 2x2 rib. How best to do this maintaining the pattern?

Do you have a link to the pattern and a name? How does the pattern suggest you increase?

Increases in rib are usually done gradually so it looks like the new ribs grow out of the old ones. Different patterns do this differently though so that’s why a link would help.
