Find the odd man out. 445, 221, 109, 46, 25, 11, 4


A) 46

B) 221

C) 445

D) 11

Answer:

Option A

Explanation:

To get the 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
