If ( 0 ), and ( -1=( 2 -1) ) then ( = )

Options

  1. A(n + 8 , n Z )
  2. B(2 n + 4 ) or (2 n , n Z )
  3. C(2 n + 8 , n Z )
  4. D(2 n - 4 ) or (2 n , n Z )

Correct answer

B. (2 n + 4 ) or (2 n , n Z )

Step-by-step solution

If ( 0 ) and ( -1=( 2 -1) ) ( array ll 1- =( 2 -1) 2 ^2 2 =( 2 -1) 2 2 2 array ) ( Either 2 =0 or 2 = 2 -1 ) ( Either 2 =n , n Z ) ( or 2 =n + 8 , n Z ) ( =2 n + 4 ) or (2 n , n Z ) Hence, option (2) is correct.
