First big project, stuck on the Raglan. Could some simplify it please?

Dec 2 sts at the beg of the next 2 rows.
Dec at each end as foll, 1st in from edge.

[1st twice every 2nd row, 1st once every 4th row] 3 times and then 1st 14 times every 2nd row.

Please can someone explain this simply. I’ve been staring at it for hours.

Welcome to KnittingHelp!
These can certainly be confusing. After you dec 2 at the beginning of the next 2 rows, call the next row, row 1. Dec at each end on rows 1,3,7, then 9,11,15, and then 17,19,23.
For the final decreases every 2nd row x 14, dec on rows 25,27,29,31 etc until you’ve dec 14 times

Thank you so much! I’ve been staring at it for a few months now!
