Question

what row comes next in the pattern?

Explanation:

Analyze the pattern in each row

Row 1: 1 yellow heart, 1 green square.
Row 2: 1 yellow heart, 2 green squares.
Row 3: 1 yellow heart, 3 green squares.

Determine the next row

The number of yellow hearts remains constant at 1.
The number of green squares increases by 1 in each subsequent row: 1, 2, 3, ...
Therefore, the 4th row must contain 1 yellow heart followed by 4 green squares.

Answer:

1 yellow heart followed by 4 green squares
