Solution:The pattern followed here is :(1st number + 2nd number)Β² + 2 = 3rd number
(4, 5, 83) β (4 + 5)Β² + 2 β 9Β² + 2 β 81 + 2 = 83
(5, 5, 102) β (5 + 5)Β² + 2 β 10Β² + 2 β 100 + 2 = 102
Similarly,
(8, 3, 123) β (8 + 3)Β² + 2 β 11Β² + 2 β 121 + 2 = 123
Hence, "(8, 3, 123)" is the correct answer.
