pattern help please

Hi wondered if anybody could help. In a pattern I am working on I have 15 stiches left and the pattern says
Dec1 st at neck edge of next 4 rows, then on foll 2 alt rows, then on 1 foll 4th row and at the same time dec 1st at raglan armhole edge of 4th 2nd and foll 5 alt rows. 2 sts. What does it mean?

For the neck dec, call the next row, row 1. Dec at the neck wdge on rows 1,2,3,4, then rows 6, 8 and finally row 12. The raglan dec doesn’t make sense to me, 4th 2nd?e

thank you so much for your reply. sorry I wrote the last bit wrong. It is and at the same time dec 1st st at raglan armhole edge of 2nd and foll 5 alt rows.

Easy to do that.
For the raglan decreases, dec on rows 2 and 4,6,8,10,and 12

Thank you very much for your help
