Let k=1LHS=2/[(2)(3)]+[1-2/4]
=1/3+1/2
=5/6
RHS=2/[(3)(4)]
=1/6
LHS=/=RHS
Let k=2
LHS=2/[(3)(4)]+[1-2/5]
=1/6+3/5
=23/30
RHS=2/[(4)(5)]
=1/10
LHS=/=RHS
∴It is not an equality actually

This is not an equality
consider k=1
LHS=2/[(2)(3)]+[1-2/4]=1/3+1/2=5/6
RHS=2/[(3)(4)]=1/6=/=LHS
consider k=2
LHS=2/[(3)(4)]+[1-2/5]=1/6+3/5=23/30
RHS=2/[(4)(5)]=1/10=/=LHS
∴It is not an equality actually
consider k=1
LHS=2/[(2)(3)]+[1-2/4]=1/3+1/2=5/6
RHS=2/[(3)(4)]=1/6=/=LHS
consider k=2
LHS=2/[(3)(4)]+[1-2/5]=1/6+3/5=23/30
RHS=2/[(4)(5)]=1/10=/=LHS
∴It is not an equality actually
