If 7 = - 4 , then the general value of is

Options

  1. An 6 , n 3 +(-1)^ n 18
  2. Bn 3 , n 3 +(-1)^ n 18
  3. Cn 4 , n 3 18
  4. Dn 4 , n 3 +(-1)^ n 18

Correct answer

D. n 4 , n 3 +(-1)^ n 18

Step-by-step solution

7 = - 4 4 = - 7 4 =2 4 3 4 (1-2 3 )=0 4 =0 or 3 = 1 2 4 =n or 3 =n +(-1)^ n 6 = n 4 or n 3 +(-1)^ n 18
