Solution:The pattern followed here is :(1st number)² - (2nd number ÷ 2)³ = 3rd number
(12, 8, 80) → (12)² - (8 ÷ 2)³ ⇒ 144 - 4³ ⇒ 144 - 64 = 80
(16, 10, 131) → (16)² - (10 ÷ 2)³ ⇒ 256 - 5³ ⇒ 256 - 125 = 131
Similarly,
(9, 6, 54) → (9)² - (6 ÷ 2)³ ⇒ 81 - 3³ ⇒ 81 - 27 = 54
Hence, "(9, 6, 54)" is the correct answer.
