Вычисли: (2 × 2) + 1; (2 × 2) + 9; (2 × 4) + 13; (2 × 5) + 19; (2 × 6) + 25; (2 × 7) + 31; (2 × 8) + 37; (2 × 9) + 43; (2 × 10) + 49; (2 × 10) + 57.

(2 × 2) + 1 = 4 + 1 = 5
(2 × 2) + 9 = 4 + 9 = 13
(2 × 4) + 13 = 8 + 13 = 21
(2 × 5) + 19 = 10 + 19 = 29
(2 × 6) + 25 = 12 + 25 = 37
(2 × 7) + 31 = 14 + 31 = 45
(2 × 8) + 37 = 16 + 37 = 53
(2 × 9) + 43 = 18 + 43 = 61
(2 × 10) + 49 = 20 + 49 = 69
(2 × 10) + 57 = 20 + 57 = 77
