Solution:The pattern followed here is :(a, b, c) → [{(b - a) × 6} + a] = c
(7, 41, 211) → [{(41 - 7) × 6} + 7] ⇒ 34 × 6 + 7 = 211
(12, 66, 336) → [{(66 - 12) × 6} + 12] ⇒ 54 × 6 + 12 = 336
Similarly,
(11, 61, 311) → [{(61 - 11) × 6} + 11] ⇒ 50 × 6 + 11 = 311
Hence, "(11, 61, 311)" is the correct answer.
