14. Jodie makes 4 patterns using these straight sticks ▬.

Patterns 1 to 4 made of sticks: each pattern is an L shape of squares, with a column of 3 squares and a bottom row that gains one extra square each time (Pattern 1 has 4 squares, Pattern 2 has 5, Pattern 3 has 6, Pattern 4 has 7)

Jodie has 90 sticks left after making patterns 1, 2, 3 and 4.
She continues this sequence of patterns, starting with pattern 5.

How many more complete patterns can Jodie make before she runs out of sticks?
You must show all your working. [3]
