Kyle is making some patterns out of squares. He has made 3 rows so far.

a. Find an expression, in terms of n, for the number of squares required to make a similar arrangement in the nth row.

b. Kyle counts the number of squares used to make the pattern in the kth row. He counts 301 squares. Write down the value of k.

c. In the first q rows, Kyle uses a total of p squares.

i. Show that q² + 2q − p = 0.

ii. Given that p > 1520, find the minimum number of rows that Kyle makes.
