sweater sleeves - trouble understanding pattern

by Ruth

hello


I have picked up knitting again after 25 years and started making my first sweater but I am having trouble understanding the pattern while working on the sleeves. It reads as follows:
cast on 31 stitches, work in rib for 4 rows (I get that part)

increase 1 stitch at each end of the 5th and 3 following 6th rows, then 0 every following 8th row to 49 stitches

Does this mean:

I knit 4 rows
in the 5th row I increase with 2 stitches (1 at each end) ->

makes 33 stitches

I knit 5 rows and in the 6th row I increase with 2 stitches (1 on each end) ->

makes 35 stitches

I knit another 5 rows and do the same in the 6th row I increase with 2 stitches (1 on each end) ->

makes 37 stitches

I do it one more time: I knit another 5 rows and do the same in the 6th row: I increase with 2 stitches (1 on each end) ->

makes 39 stitches

I am misinterpreting this because I need to end up with 49 stitches....

Kindly explain how I need to read this correctly.

Thank you very much for your input!

YOUR ANSWER

It appears to me that there might be an issue with the wording on your pattern, either a typo or an editing issue probably. It happens sometimes.

If it was my project I would just continue as you have to this point, increasing on every 6th row until you have 49 stitches.
