Help with crochet pattern

I am making a sleeve for a shrug and am having problems. Here is what the pattern says:
Row 1: (Right side): Dc in fourth ch from hook (3 skipped chs count as first dc) and in each ch across. {26} dc.

Row 2: (Increase row): Ch 1, turn; 2 sc in first dc, sc in next dc and each dc across to last dc, 2 sc in last dc: {28} sc.

Row 3: Ch 3, turn; dc in next sc and each sc across.

This next step is where I am having problems in the pattern:

Continue to increase one st at each edge in same manner, every other row, {15} times more; then increase every fourth row, {1} time(s): {60} sc.

Do I repeat rows 1 and 2 and increase on row 2?
Please help.
