#a

  • a(1)=1
  • a(n)=3a(n-1)


\\ \sf\longmapsto a(2)=3a(1)=3(1)=3


\\ \sf\longmapsto a(3)=3a(2)=3(3)=9


\\ \sf\longmapsto a(4)=3a(3)=3(9)=27


\\ \sf\longmapsto a(5)=3a(4)=3(27)=81

#b

  • b(1)=1
  • b(n)=-2+b(n-1)


\\ \sf\longmapsto b(2)=-2+b(1)=-2+1=-1


\\ \sf\longmapsto b(3)=-2+b(2)=-2-1=-3


\\ \sf\longmapsto b(4)=-2+b(3)=-2-3=-5


\\ \sf\longmapsto b(5)=-2-5=-7
