Observe the following figures and their corresponding formulas. According to the rule you found, use n to represent 1 + 8 + 16 + 24 + +8N (n is a positive integer)______ ．

When n = 1, 1 + 8 × 1 = 9 = 32 = (2 × 1 + 1) 2, when n = 2, 1 + 8 × 1 + 8 × 2 = 25 = 52 = (2 × 2 + 1) 2, when n = 3, 1 + 8 × 1 + 8 × 2 + 8 × 3 = 49 = 72 = (2 × 3 + 1) 2, when n = 4, 1 + 8 × 1 + 8 × 2 + 8 × 3 + 8 × 4 = 81 = 92 = (2 × 4 + 1) 2  and so on, the formula of n is 1 + 8 +
