Find the odd man out. 445, 221, 109, 46, 25, 11, 4
Answer/Solution
46
Steps/Work
Explanation :
To obtain next number, subtract 3 from the previous number and divide the result by 2
445
(445-3)/2 = 221
(221-3)/2 = 109
(109-3)/2 = 53
(53-3)/2 = 25
(25-3)/2 = 11
(11-3)/2 = 4
Clearly, 53 should have come in place of 46
