Question about reading a pattern

[Darlazero]

I am new to knitting and am trying to read my first pattern. I have completed the ruffle rows of the Misti Ribs and Ruffles Scarf. The instructions detail the pattern for Row 1 and then Row 2. The next direction describes ending the scarf. So, my question is this...do I repeat R2 instructions until I end the scarf (R1,R2,R2,R2...) or do I repeat the instructions for R1 and R2 (R1,R2,R1,R2...)

Thanks for your help!

Here's the link to the pattern:
