Вычисли: (2 × 1) + 1; (2 × 2) + 7; (2 × 3) + 13; (2 × 4) + 19; (2 × 5) + 25; (2 × 6) + 31; (2 × 7) + 37; (2 × 8) + 43; (2 × 9) + 49; (2 × 10) + 55.

(2 × 1) + 1 = 2 + 1 = 3
(2 × 2) + 7 = 4 + 7 = 11
(2 × 3) + 13 = 6 + 13 = 19
(2 × 4) + 19 = 8 + 19 = 27
(2 × 5) + 25 = 10 + 25 = 35
(2 × 6) + 31 = 12 + 31 = 43
(2 × 7) + 37 = 14 + 37 = 51
(2 × 8) + 43 = 16 + 43 = 59
(2 × 9) + 49 = 18 + 49 = 67
(2 × 10) + 55 = 20 + 55 = 75
