By studying the clues, you know that if there are 2 stars in the first row, one possibility is that there are 3 stars in the next row, 2 stars in the following row, and so on. That pattern could look like:

2 + 3 + 2 + 3 + . . .

Using this same pattern, is it possible to reach a sum of 50 stars? How about:

3 + 4 + 3 + 4 + . . .?
