The logic used here is the difference between the third and second number is twice the difference between the second and first number. (44, 89, 179) = 89 - 44 = 45 179 - 89 = 90 ( 45 × 2 = 90) Option 1 does not follow the pattern. (84, 116, 181):
116 - 84 = 32 181 - 116 = 65 ( 32 × 2 = 64) It does not follow the pattern. Hence, (84, 116, 181) is the odd one out. |
