I have a question:
what is lim (n--->infinity)= 1/(3+(-1)^n))? My opinion that this limit does not exist.

if n∈Z (Z=Integer) then we have two answer for equation
1) if n=Even then answer=1/4
2) if n=Odd then answer=1/2
if n∈R (R=Real) then equation is undefined
for example: (-1)^1/2 does not exist.
