Solution:The pattern followed here is :[{3rd number - (2nd number × 2)} ÷ 1st number] = 200
(4, 14, 828) → [{828 - (14 × 2)} ÷ 4] ⇒ {(828 - 28) ÷ 4} ⇒ 800 ÷ 4 = 200
(3, 10, 620) → [{620 - (10 × 2)} ÷ 3] ⇒ {(620 - 20) ÷ 3} ⇒ 600 ÷ 3 = 200
Similarly,
(2, 50, 500) → [{500 - (50 × 2)} ÷ 2] ⇒ {(500 - 100) ÷ 2} ⇒ 400 ÷ 2 = 200
Hence, "(2, 50, 500)" is the correct answer.
