The positive difference of the fourth powers of two consecutive positive integers must be divisible by

(A) one less than twice the larger integer

(B) one more than twice the larger integer

(C) one less than four times the larger integer

(D) one more than four times the larger integer

(E) one more than eight times the larger integer
\(81 - 16 = 65\)

Smaller no is 2 ; larger no is 3

(A) 65/5 = 13
(B) 65/6 = Not Divisible
(C) 65/11 = Not Divisible
(D) 65/13 = 5
(E) 65/33 = Not Divisible

Answer must be between (A) and (D) , plug in diff nos and check -

Let, Smaller no is 1 ; larger no is 2

16 - 1 = 15

(A) 15/5 = 3
(D) 15/9 = Not divisible

Hence, Answer must be (A)
