(3.6) = 18
(4.6) + (2.4) = 32
(5.6) + (2.4) + (3.4) = 50
(6.6) + (2.4) + (3.4) + (4.4) = 72
(7.6) + (2.4) + (3.4) + (4.4) + (5.4) = 98
(8.6) + (2.4) + (3.4) + (4.4) + (5.4) + (6.4) = 122
(9.6) + (2.4) + (3.4) + (4.4) + (5.4) + (6.4) + (7.4) = 150
(10.6) + (2.4) + (3.4) + (4.4) + (5.4) + (6.4) + (7.4) + (8.4) = 182
