The 3rd number is twice the absolute difference of the 1st and 2nd number. [36, 18, 36] → 2 X (36 – 18) = 2 X 18 = 36. [54, 29, 50] → 2 X (54 – 29) = 2 X 25 = 50. (62, 31, 64) → 2 X (62 – 31) = 2 X 31 = 62. (47, 23, 48) → 2 X (47 – 23) = 2 X 24 = 48. (79, 58, 42) → 2 X (79 – 58) = 2 X 21 = 42. (85, 40, 90) → 2 X (85 – 40) = 2 X 45 = 90.
