The factors of 12 in increasing order are 1,2,3,4,6,12
i.e. a total of 6 factors
We see that
product of 1 and 6th number =12
product of 2nd and 5th number = 12
product of 3rd and 4th no = 12
and so on
What happens if the no of factors are odd
Plz extend this logic to determine which numbers will have odd no of factors..

Along a corridor there are 100 doors marked as 1,2,3...100. As u know the doors can be in two states...open or close... initially all doors are closed. Person no 1 changes the state of all doors that are a multiple of 1 i.e. basically all doors. Person number 2 then changes the state of all doors that are a multiple of 2. This happens till person number 100.
Now how many doors are closed..
Hint.. Try to find for a particular door, how many persons will change the state...
A function f(x) is defined as (x + 1) × f(x + 1) + x × f(x) + (x – 1) × f(x – 1) = 0 for x 2 ≥ . If f(1) = 40
and f(6) = 180, find the value of f(14).
(a) –80 (b) –160 (c) –1120 (d) Cannot be determined
