if we check the difference between all the given numbers. it is as follows 144 , 100 , 64 , "41" , "11" ,4 hear we can see that the differences are the perfect squares.... so the answer i.e wrong number is 440. that should be replaced by 445 then 41 will be replaced by 36 & 11 by 16..

it is the form of square of even numbers (n<=12),and it is subtracted with previous number.So the the odd one is 440 because 481-64=445
