18. G(0)=-1, G(1)=1, G(N)=G(N-1) - G(N-2), G(5)= ?

• G(2) = G(1)-G(0) = 2
  Similarly find G(3) then G(4) and G(5)
  G(5)=-2

• G(2)=G(1)-G(0)=1-(-1)=2
  G(3)=G(2)-G(1)=2-1=1
  G(4)=G(3)-G(2)=1-2=-1
  G(5)=G(4)-G(3)=-1-1=-2

• m sorry... the ans is -2... it is mistyped by me

• G(2) = G(1)-G(0) = 1- (-1)= 1+1 =2
  G(3) = G(2) - G(1) = 2-1 =1
  G(4)= G(3) - G(2) = 1-2 = -1
  G(5) = G(4) - G(3) = -1 - 1 = -2

• given G(0)=-1,G(1)=1 AND G(N)=G(N-1) - G(N-2)
  put N=2
  G(2)=G(1)-G(0)
  =1-(-1)=2
  G(3)=G(2)-G(1)=2-1 =1
  G(4)=G(3)-G(2)=1-2=-1
  G(5)=G(4)-G(3)=-1-1=-2,
  HENCE G(5) = -2

• G(5)=-3
  as G(2)=2, G(3)=1,G(4)=-1. Putting these values we get G(5)=-3
• 9 years agoHelpfull: Yes(0) No(1)
• G(5)=G(4)-G(3)
  similarly find the values of G(4), G(3), G(2).
  putting these values we get, G(5)= 2.

• G(5)=G(5-1)-G(5-2)-G(5-3)-G(5-4)-G(5-5)
  =G(4)-G(3)-G(2)-G(1)
  = -2
• 9 years agoHelpfull: Yes(0) No(0)
• G(5)=G(5-1)-G(5-2)=G(4)-G(3)
  =7-5
  = 2.

• Clearly its -2
• 9 years agoHelpfull: Yes(0) No(1)
• G(N)=G(N-1) - G(N-2)
  G(5)= G(4)- G (3)
  = {G(3) -G(2)}-G(3)= -G(2)
  = - {G(1)-G(0)}
  = - {1-(-1)}
  = -2
