Ans: C. 46

4*2+3 = 11
11*2+3 = 25
25*2+3 = 53
53*2+3 = 109
109*2+3 = 221
221*2+3 = 445

the diff b/w (445-221)=224
the diff b/w (221-109)=112{which is diff of prev/2 ie 224/2}
the diff b/w (109-46)=63 {which is not the diff of previous/2}
the diff b/w (46-25)=21
the diff b/w(25-11)=14
the diff b/w (11-7)=7 {which is the diff of previous/2}
from this we know that 46 is wrong number because 112/2 gives 56 .
but in question 109-46 gives 63 so it clear that 46 is wrong
in order to find the correct num 109-x=56
then x=53
53 is correct in place of 46

Every number multiply with 2 and add 3 we will get answer but 25*2+3=53 .so 46 is incorrect.
